Whipsaw

New York... Newark... Pittsburgh... St. Louis. Vivian Palmer and Ross McBride are on the lam, trying to put daylight between themselves and pursuing coppers and a rival gang of jewel thieves. But Ross isn't a criminal; he's a G-Man posing as a crook to trick Vivian into leading him to her bosses. And Vivian isn't a dupe. She's wise to Ross's scheme. (official distributor synopsis)
