After Jack and Eleanor Carroll entertain their perpetually squabbling friends, Eddie Roberts and Sally Beaver, they decide to show the couple how their bickering appears to others by staging a phony row the next time they dine together. Although the ruse succeeds in changing Eddie and Sally's attitudes, it also leads to a real fight between Jack and Eleanor when Jack insults Eleanor's mother. Furious, Eleanor leaves home and returns to her mother's side on the first day of Jack's long-awaited vacation. On Eddie's advice, the bumbling Jack, who has acquired a mine sweeper in order to locate some buried treasure in Reno and finance his own rabbit farm, then leaves for Nevada without Eleanor. Before Jack arrives at the Bar Nothing Dude Ranch, he stops at a local bank and becomes a witness to a bank robbery. The robbers--Joe, Bunny Wells and Angel--flee from the police, bury the stolen money near the ranch and, posing as tourists, check into the ranch. Later, Jack finds the robbers' suitcase of money and silver with his mine sweeper and assumes it is the buried treasure. After placing the suitcase in the ranch's safe, Jack is questioned by both the robbers, who recognize him from the bank, and the sheriff, who wants to know if Jack can identify the crooks. Although he brags to the sheriff that he can identify the crooks, Jack treats Joe, Angel and Bunny as friends and nonchalantly tells Bunny that he has a suitcase full of money. Eleanor, who has learned of Jack's whereabouts from Eddie, then arrives at the ranch concerned that he has come to Reno for a divorce. When Eleanor hears that Jack is in the bar with his "wife," as Bunny has identified herself, she confronts him. Jack tries to convince her of his true mission by showing her the money, but discovers that he has been mistakenly given a suitcase filled with women's clothes. While Jack then tries to retrieve his suitcase from the wife of a jealous sailor and explain matters to Eleanor, the robbers plot to steal back the money. At the same time, an officer assigned to watch Jack becomes determined to trap Jack with "wife" Bunny. As soon as Jack gets his hands on his suitcase, the officer catches him leaving the sailor's room and handcuffs him to his bedpost. By the next morning, Jack has escaped and made up with Eleanor, but is forced at gunpoint to return the suitcase to the robbers and is locked in Eleanor's room. Jack breaks out, however, and lands on top of the dude ranch's stagecoach, which is carrying the fleeing robbers. After a furious chase involving Jack, the sheriff and Eleanor, the robbers are apprehended and Jack is given a $5,000 reward.
