Step by Step is a 1946 American drama film directed by Phil Rosen, written by Stuart Palmer, and starring Lawrence Tierney, Anne Jeffreys, Lowell Gilmore, Myrna Dell, Harry Harvey, Sr. and Addison Richards.

A police officer comes at his request and, at the house, impostors claiming to be the senator, his driver and his secretary convince the policeman that Johnny is mentally disturbed, perhaps because of his war experience.

Johnny sneaks back into Senator Remmy's home, donning clothes he finds laying around.

The chauffeur is tied up, the Senator is unconscious and the government operative, James Blackton is dead.

The spies decide the list must be in the jacket and then discover Evelyn and Johnny's hiding place at the motel.

They find a letter Johnny had dictated to the Senator taken down in shorthand by Evelyn explaining true situation.

Captain Simpson helps them believe Johnny’s explanation by mentioning fresh fish discarded by the enemy agents which could not have been caught in the salt water ocean.

The police arrive with Captain Simpson to place all the enemy agents under arrest after a gun battle.
