Maggie is the only cow left on the Dixon Ranch after Alamida Slim (a cattle rustler capable of stealing 500 in a single night) stal all the rest of Dixon's cattle. Mr. Dixon sells Maggie to Pearl, a kind and elderly woman that runs a small farm called Patch of Heaven.
The local Sheriff arrives to tell Pearl that her bank is cracking down on debtors. Pearl has three days to pay the bank $750, of her farm will be sold to the highest bidder. Hearing this, Maggie convinces the other cows on the farm (Grace, a happy-go-lucky character, and Mrs. Calloway, who has had leadership gone to her head) to go to town to attempt winning prize money at a fair.
While the cows are in town, a bounty hunter named Rico (who Buck, the Sheriff's horse, idolizes) drops a criminal off and collects the reward. Stating he needs a replacement horse to go after Alamida Slim while his own horse rests, he takes Buck. When Maggie find out that the reward for capturing Slim is of exactly $750, she convinces the other cows to try to capture him to save Patch of Heaven.
That night, they hide among a large heard of steers, when Alamida Slim appears. Before any of them can do anything, Slim begins a yodeling song which sends all the cattle (except Grace, who is tone deaf) into a trance that causes them to dance madly and follow Slim anywhere. Grace is able to bring Maggie and Mrs. Calloway back to their senses just before Slim closes the path behind him with a rockslide to stop Rico and his men from chasing him.
As Rico discusses with his men what his volgende verplaats will be, Buck starts talking with Maggie, Grace, and Mrs. Calloway as old vrienden and miming actions. This causes Rico to believe Buck is frightened door cows, and sends Buck back to the Sheriff. Buck escapes, determined to capture Slim for himself to prove his worth. Maggie, Grace, and Mrs. Calloway are left behind, but they meet a peg-legged rabbit named Lucky Jack, who leads them to the Slim's hideout mine.
At the mine, Slim reveals that he has been stealing all cattle from his former patrons. When his former patrons can't support their land anymore, he buys the land when it is auctioned off, under the guise of the respectable-looking Mr. O'delay, using the very money he gets from selling the cattle he stole.
After arriving to Slim's hideout, the cows capture Slim. They run off with Slim's accomplices and buyer in pursuit on a steam train. Rico arrives. When the chase stops, Rico is revealed to work for Slim.
Slim dons his O'delay costume and leaves the cows stranded in the middle of the desert with the train, while he goes to attend the auction. However, the cows arrive using the train to the farm and expose Slim. Slim is arrested door the police, and Patch of Heaven is saved door the reward money. This film is well boring indeed. I hate it. It should never have been made. Don't watch it at home, kids.
