Don't Raise the Bridge, Lower the River

George Lester (Jerry Lewis) is an American living in Britain. His passion is get-rich-quick schemes, and they have caused financial and personal grief for he and his wife, Pamela, (Jacqueline Pearce) who is considering divorce if he continues with them.

Willy Homer (Terry-Thomas) is a conman who plans to help George raise some quick cash by selling plans for a drill to a group of Arabs. The plans, which were stolen, are smuggled to Lisbon with help from his accomplice, Fred Davies (Bernard Cribbins). As they are about to trade the plans, they realise that they are being double-crossed. A series of chases follows, and eventually the plans are revealed to be worthless to everyone.

Distraught, George finds comfort in his wife and promises to never embark on any more schemes, but Willy shows up at his door with another one.
