Buck Russell(John Candy) is not the most reliable and trustworthy person around, and when Cindy Russell(Elaine Bromka) (his sister in law) and Bob Russell(Garrett M. Brown) (his brother) use him as a last resort to babysit their children Miles(Macaulay Culkin), Maizy(Gaby Hoffmann) and Tia(Jean Louisa Kelly) (who is a rebellious 16 year old), Buck agrees to fill in while Cindy and Bob go to Indianapolis to visit Cindy's ill father. While over at the house, Buck does his usual routines including going to smoky bowling alleys and smoking cigars. Yet, the longer and longer he is around with Miles and Maizy and the more he witnesses Tia slowly get seduced by her boyfriend Bug, Buck learns responsibility and more to life than just being an eligible bachelor and having fun.
