Saturday Night Live star Dana Carvey had his first leading role on the big screen in this comedy. Eddie (Carvey) and Lou (Todd Graff) are a pair of small-time con artists deep in debt to Pinkie (Mike Bacarella), a loan shark. During a lean period, Eddie and Lou resort to breaking and entering to make some money, but as they're clearing out a house, they overhear the answering machine announce that the owner is away on business for a few weeks -- and the housesitter won't be able to stop by. Eddie and Lou settle in and enjoy their good fortune, which just gets better when Milt (Robert Loggia) pays a visit. Milt assumes that Eddie is the housesitter, who is a close friend of his son. Eddie is soon introduced to Milt's beautiful daughter, Annie (Julia Campbell), and Milt decides that Eddie is executive material at his successful manufacturing firm. Soon Eddie starts to wonder if he should go on lying to the people he's come to like -- and there's the little matter of the 60,000 dollars that Eddie and Lou swiped from Pinkie's car. Opportunity Knocks also features Milo O'Shea and James Tolkan.
