Trampa mortal.

A former convict, named Raul Vela, and a cabaret singer, called Clara, are a couple who tries to lead a normal life. He has found an employment and she wants to leave the cabaret. One day an old chief, who wants to disappear, proposes him to justify his supposed death in a supposed accident. In exchange, Raúl will receive one hundred thousand pesetas as gratification. Raul refuses to engage in the deception. Shortly after, he reads in a newspaper about the death of Cervera, which makes the police relate him to the case.
