Four relatives find themselves going to unusual lengths to inherit a fortune in this British comedy. Henry Russell (Hugh Griffith) was a practical joker all his life, and his sly sense of humor is hardly stilled by his death; when his four closest relatives gather for the reading of the will, they discover that each is to be left $140,000 -- but, as always, there are strings attached. His sister Agnes (Fay Compton) has always treated her hired help with an attitude bordering on contempt, so Henry leaves her the money with the proviso that she must first work as a maid for 28 days. His cousin Deniston (Alastair Sim) writes detective novels for a living, so Henry insists that he get a clearer perspective on how bad guys live -- to collect his inheritance, he must spend four weeks in prison. Herbert (George Cole), a milquetoast clerk at a bank, will only receive his share if he's able to pull off a robbery at his place of employment. And Simon (Guy Middleton), a confirmed ladies' man, must marry the first girl he meets (and stay married to her) if he's to collect his $140,000. Keep an eye peeled for a youthful Audrey Hepburn, who has a bit part as a cigarette girl.
