Chester Beatty and Tessie Weeks have been engaged for 5 years and going together for 15 years before that. Chester is reluctant to burden Tessie with marriage because of his secret problem. He is a sleepwalker. When Tessie finally does rope Chester into marriage, he can`t get time off from his boss of 26 years, Mr. Frisbee. To resolve the problem, Chester sets out to impress his boss by securing a big sales contract of glass eyes. He takes Tessie and follows the rich doll company owner Horace B. Stanton to a lakeside resort and befriends him. However, his sleep-walking makes him a prime suspect in a thievery/murder case.
