After a millionaire practical joker dies, his fortune is divided among four heirs who must carry out his zany instructions to cash in.

Famed practical joker Henry Russell leaves 50,000 pounds to each of his four surviving relatives. But his will has one last joke - they each have to undertake a task completely out of character within a month. As each sets out on their objective they find that quite apart from the promised riches, they are unexpectedly getting a lot out of the challenge. All except caddish Simon Russell, that is.—Jeremy Perkins {J-26}
