The Trap is a 1946crime film directed by Howard Bretherton and starring Sidney Toler and Victor Sen Yung. The main premise is that two members of a show troupe are murdered, and detective Charlie Chan is called in to solve the case. The title credit mentions "Charlie Chan" as appearing in the film, as if he were an actor and not a fictional character portrayed by Toler. This was Toler's 22nd and final appearance as Chan, and his final film of any kind. Suffering from cancer during his last few films, Toler was often so weak that he could hardly walk or say his lines coherently.

Another member of the theatre group, Clementine, discovers Marcia dead and strangled on the beach, with a silk cord still around her neck.
