Trapped (1949)

A taut and tough noir. The Feds are on a case of counterfeit dollar bills, they need the plates to stop the near perfect fake bills being printed. They arrange with the plate's creator Stewart (Lloyd Bridges), for him to help the Feds track down the plates in return for parole. The Feds arrange for him to "escape" and he links up with his old squeeze Dixon (Barbara Payton).

Unknown to Stewart and Dixon, the Feds already have a line on Dixon. Agent Downey is posing as small-time hustler Hackett (John Hoyt) and he arranges for himself to become part of Stewart's plan to get the plates back from Sylvester (James Todd). Downey and the Feds' plan runs into trouble when Stewart decides that escaping to Mexico with Dixon and a pile of cash is preferable to going back to the jail...

A great crime film with plenty of double dealing and intrigue, not a small amount of violence too. All you want in a really good noir crime film.
