Rigsby is the owner of a sleazy boarding house whose tenants include Philip, a black medical student, and Ruth Jones, a tutor at the local college upon whom Rigsby has set his sights. Following the departure of recent tenant Alan, his place in the house is quickly snapped up by art student John.
Unfortunately for Rigsby, Miss Jones, somewhere in her 30s, finds fellow tenant and African prince, Philip far more to her liking; and unfortunately for Miss Jones, Philip would far rather spend his time alone or with new room-mate John! The sole purpose in John's life, meanwhile, seems to be losing his virginity to girlfriend Sandra.
The fragile romantic alliances and balance of power in the house are upset when the well-spoken Mr Seymour arrives in search of a room. Miss Jones quickly falls for the suave newcomer, and he for her savings book!
