Dann Mulvey (William Scott), just released from prison, is falsely accused of murder. The real culprit is the least-suspected person, who makes a deathbed confession.
Adapted from the Fannie Hurst story of the same name, Mannequin is the story of Joan Herrick, kidnapped in infancy from her wealthy parents and raised by a slatternly slum woman. The film is still extant.
Because Dan McDowell is unable to operate the new mechanized fire equipment, he is retired with a small pension; his son, Johnny, quits school to work in the fire department; and his old horse, Bullet, is sold to a dirt-hauler. Dan is charged with stealing Bullet and is jailed, but he is cleared in time to give valuable aid in a fire that traps Johnny's sweetheart, June Rutherford.
