The Glass Key (1942) Alan Ladd, Veronica Lake, Brian Donlevy, William Bendix

After falling for Janet Henry, the daughter of reform candidate for governor Ralph Henry, shady political boss Paul Madvig is determined to help Henry get elected. Paul’s right-hand man, Ed Beaumont, rightly distrusts both Janet and her father, and suspects that they are stringing Paul along only to dump him after the election. Janet becomes engaged to Paul, but is put off by his crudity. She is attracted to the more sophisticated Ed, who fends off her advances out of loyalty to Paul. The deluded Paul boasts that Henry has practically given him the key to his house, but Ed warns him that it is liable to be a glass key, one that can break at any moment. When Paul tells one of his supporters, the gangster Nick Varna, that he is cleaning up the city and that Varna will no longer receive protection from the police, Ed grows even more concerned. Complicating matters further, Ralph’s ne’er-do-well son, Taylor, owes Nick for gambling debts, while Paul’s young sister, Opal, is in love with Taylor. Paul has told her to stay away from Taylor, but she defies him. Opal becomes fearful about what Paul might do to Taylor.
