A zany, fast-moving comedy of confusion. When Tom, an Elvis fanatic, and Alice his fiancee are unable, due to fog, to fly to Miami for an Elvis Convention, they arrive back at Tom's flat to find they have inadvertently picked up the wrong suitcase at the airport and are now in possession of half a million dollars. Confusions arise when Auntie arrives with a bag containing $20,000 as does Frankie, a thug working for the owner of the suitcase dollars, and it takes Inspector Hendy to sort everything out.
