Ralph is a classical pianist who is having trouble with his arm which leaves him. The arm is found by Peter and Georgina who wrap it securely in a manner all too similar to the leg of lamb which is planned for dinner by the maid. Having discovered its whereabouts, Ralph goes to the house to claim his arm. His arrival sets off a classic French farce involving Peter, Georgina, the arm, the lamb, the dog, the maid, the "fridge," and the oven.
