Shadow of the Law is a 1930 American pre-Code film directed by Louis J. Gasnier and starring William Powell, Richard Tucker, and Regis Toomey.

Mechanical engineer James "Jim" Montgomery escorts attractive blonde Ethel George to her apartment, one floor up from where he himself lives.

When Police Lieutenant Mike Kearney arrives, Jim makes a mistake and claims there was nobody else in the room.

Two years later, Jim is in Suffolk, North Carolina, working as mill manager "John Nelson".

Private detectives have located Ethel George, but now he needs someone he can trust completely to go see her in New York and make her tell the truth.

She tells Jim privately that she wants $50,000, a sum he does not have, but she points out that Colonel Wentworth would pay that much to protect his daughter.
