 When Lyle Endicott is fired from his job at an art museum, he has his girlfriend Pamela type a phony letter of recommendation for him. He takes the letter to the invalid Martha Cheney, whom he met at the museum. Lyle knows that the museum has been eagerly trying to buy a valuable vase that Miss Cheney received from her father. While working for her, Lyle sets out to isolate her from everyone else, so that he can take advantage of the situation for himself.
