The Masked Bull, Saddle Sore & Boot Hill Buzzard held up the Mesa Stagecoach and are being chased by Moo & crew. While Sadle Sore & Boot Hill Buzzard are captured, while the Masked Bull gets away. The two henchmen are jailed by Moo & crew but Mayor Bulloney allows them to be released immediately against Moo's advice. Moo Montana, upset at the Sheriff and Mayor's disregard for the Code of the West, heads to Lily's Saloon, where he runs into Dakota and Cowlorado. He keeps trying to tell his friends his troubles, but no one seems to want to listen. Dakota and Cowlorado rush off together to fix Dakota's saddle and Lily leaves to go wash dishes, leaving Moo to celebrate his 10 year anniversary as Marshall alone. He feels like no one appreciates his hard work and contemplates hanging up his star since he's not sure he even makes a difference anymore.

Sheriff T-Bone of Miller Glen, Moo's hometown, will be retiring soon and Bessie Bluebell brings him some lunch. Bessie's brothers, Frank and Beans, come running in to report that Bat Blastagun and his goons, Sid Arachnid and Gil A. Monster have ridden into town and are causing trouble. T-Bone, rushes out to put a stop to their trouble-making and Bat has him thrown in the town well. Bessie steps in to try to stop them, but is not effective, Frank and Beans try to protect her but all three are tied up and trapped. Bessie, Frank and Beans escape and Bessie sends a telegram to Moo for help dealing with Bat Blastagun. Moo rushes off immediately to help his home town and his old love interest, Bessie. Meanwhile, Lily, Dakota and Cowlorado are busy planning a surprise party for Moo's 10 year anniversary as a Marshall. They have found a note Moo left saying he was going to Miller Glen and they worry that he was upset with them over "forgetting" his anniversary.

Sheriff T-Bone had taught Moo everything he knows about being a cowboy and was a real father figure to him. As Moo rides into Miller Glen it appears deserted until Frank and Beans crawl out of hiding and explain about Bat Blastagun and his outlaws. Moo meets up with his mentor T-Bone and the Sheriff asks Moo to stay on as Sheriff in Miller Glen when he retires. Bat and his outlaws are divvying up loot and reveal their plan to destroy Miller Glen in a plan to scare all of the Mesa into giving them protection money.

Moo is eating with Bessie and her brothers and all the townsfolk bring food to let Moo know how much they appreciate his help and want him to stay on as Sheriff. Moo offers to train Frank and Beans as Deputies. T-Bone, Moo, Frank and Beans are ready for Bat and his gang and puts a quick stop to their evil plans, but Moo is sure they will be back. Bat has been embarrassed by Moo and plans to get even.

Meanwhile, Dakota and Cowlorado lament over how out of hand The Masked Bull has gotten in Moo's absence. Sheriff Terrorbull gives Dakota and Cowlorado a hard time since they have been unable to capture the Masked Bull. The telegraph operator rabbit rushes up to inform Dakota, Cowlorado and Lily that Moo is thinking of agreeing to take the Sheriff job in his hometown of Miller Glen and may be marrying Bessie.

Bat, Sid and Gil kidnap Bessie and hold her as bait in Bat Wing Cave to lure Moo into their trap. He goes alone to save Bessie. Moo is able to save Bessie but Bat and gang give chase. Bessie helps them get away by lassoing a tumbleweed that stirs up so much dust that Bat and his goons lose the trail. Moo safely delivers Bessie to her brothers, but Moo informs T-Bone that Bat and his outlaws can't be far behind and there will be a showdown. When the 3 outlaws show, there is a tense moment until Moo single-handedly disarms Bat and his two goons while Frank and Beans lasso them. Moo places them under arrest and the whole town of Miller Glen breaks out in celebration. As the town cheers Dakota and Cowlorado ride up and see how much Miller Glen appreciates Moo's help. T-Bone and Bessie tell Moo how much they appreciate him and ask if he'll commit to being Miller Glen's Sheriff but Cowlorado butts in and tells Moo to think of Cowtown as well and how much difference he's made in his 10 years as a Marshall- Moo realizes that they knew all along about his 10 year anniversary. Cowlorado also gives Moo a letter from Mayor Bulloney begging Moo to come back. Moo can't believe the Mayor would right such a thing until Cowlorado reveals Lily threatened to run for Mayor if he didn't get Moo back. T-Bone asks Moo what his decision will be and Moo appreciates Miller Glen's offer but he's got to get back to his town. Moo is forever grateful for all that T-Bone has taught him but he's been on the trail too long to settle down. He tells Bessie he will always have a special place in his heart for her. Moo points out that Frank and Beans have had training as Deputies now and will be able to take over as Sheriff once T-Bone retires. As Moo and crew get home and step into the Tumbleweed Saloon Moo gets his surprise party.

Moo and Dakota reminisce about cattle drives while watching a cattle drive in progress. Cowlorado admits he's never been on one, when Sally Sue calls him over and gushes about how much she loves a man who knows his way around a cattle drive. Cowlorado, wanting to impress her says he's been on many and is just about to head off on another cattle drive. Just then a bull bursts through the fence, endangering Sally Sue. Cowlorado tries to impress her by stopping the bull, but is run over by the charging bull who chases Sally Sue through her house emerging out the other end in a dress. Moo steps in to rescue Sally Sue and they follow the cross dressing bull as it tears up the town and demolishes a Fine China shop. Moo and crew finally put a stop to his antics. After Cowlorado has lassoed the bull, Sally Sue tells him she was so impressed that he should call on her after his "next" cattle drive. Now Cowlorado needs to find a herd of cattle to drive.

Moo and crew are at Lily's saloon, Lily asks them to do a favor and move some livestock for her. Cowlorado is very eager to work the livestock and instantly agrees to the job, assuming that it's a cattle drive. Lily tells him to meet her behind the Tumbleweed to start the job. Moo tries to give Cowlorado advice before he embarks. Lily then shows Cowlorado Ewe Baby, her sheep, and informs him that this is the livestock he needs to deliver to Elbow's Bend. Cowlorado wants to back out because he'd be embarrassed to be seen with a female sheep. Moo reminds him that he made a promise and needs to honor it. Lily offers that if the job is too much for him he can back out- he swears no job is too big for him. He tries fruitlessly to herd Ewe Baby until Lily gives him a bottle of her homemade Sarsaparilla and says Ewe Baby loves it. Cowlorado gets laughed at by Sally Sue and some other townsfolk. Lily worries about whether Cowlorado is up to the task. Moo assures her Cowlorado can handle it. Lily explains that she strapped a lot of money under the sheep's fur for the folks at Elbow's Bend to help complete the Hospital. She has to send the money hidden on the sheep since the Masked Bull keeps robbing the Stage. Moo and Dakota decide they should catch up with Cowlorado to make sure the money gets there safely, unfortunately Boot Hill Buzzard and Saddle Sore overheard the whole conversation and tell Sheriff Terrorbull.

Soon we see the Masked Bull and his two goons chasing down Moo and Dakota as both parties catch up to Cowlorado and Ewe Baby who are trying to cross a muddy dried up pond. Cowlorado tires to carry Ewe Baby and winds up falling in. After changing, Cowlorado is once again made fun of when a couple of foxes ride by while on a cattle drive. Cowlorado comes up to a stream and not wanting to carry the sheep over again, he tosses the bottle of Sarsaparilla over the stream and the sheep jumps right in but gets stuck in moving quick sand. Cowlorado and his horse try to save her but both fall in. They get pulled into a whirlpool and finally all three get rescued by Dakota.

Moo, Dakota, Cowlorado and Ewe Baby camp-out and sing campfire songs to lull the sheep to sleep. While everyone sleeps the Masked Bull sneaks up and swaps sheep. The next morning they head out and notice that the sheep now easily jumps over streams. The cowboys feel that something's wrong and their suspicions are realized when they arrive at the hospital in Elbow's Bend and see that there is no money! They get word from Miss Lily that Ewe Baby has a rose tattoo on her shoulder and they see that someone swapped their sheep. Moo says they'll have to track down Ewe Baby and they'll need J.R.'s help.

Meanwhile the Masked Bull and his goons are herding Ewe Baby back to Cowtown since they forgot the shears. J.R. meets up with Moo and crew with his Critter Caller invention. Dakota sings into it to try to call Ewe Baby. Ewe Baby flees from the Masked Bull. Tons of sheep respond to the call and J.R. says the only way to find the right one is to shear them all. They all set to work and after many sheep, they find Ewe Baby and the money. The Masked Bull lassos Ewe Baby and demand the money in return for Ewe Baby's safety. Moo gives up the money so Ewe Baby won't get hurt. The Masked Bull starts a sheep stampede to provide a distraction for his getaway. Moo and crew have to stop they stampede so it won't destroy Elbow's Bend. The stampede is proving impossible to stop until Cowlorado has the idea to use Sarsaparilla to distract Ewe Baby and the herd and send them towards the Masked Bull. Cowlorado then stops the Masked Bull and his goons and retrieves the money. Elbow's Bend is able to complete the new Hospital. Miss Lily gives Cowlorado all the credit for getting the money there safely. Miss Lily and Ewe Baby give Cowlorado a wool sweater to thank him for a job well done.
