Homicidal criminal Charles McGraw busts out of jail, kidnapping the three people responsible for his incarceration. The hapless hostages include detective Michael O'Shea, district attorney Frank Conroy, and nightclub singer Virginia Grey. McGraw makes no secret of his plans to kill O'Shea and Conroy once he has successfully made a getaway; he has other plans for Grey, however, and for a while it seems as though she'll willingly play along with him. The cat-and-mouse game reaches its peak of tension some sixty minutes into this 65-minute thriller. Sparse and unpretentious, The Threat contained far more excitement than many a more expensive, star-studded film noir.
