When The Clock Strikes (1961)

In this crime drama, several people gather at an inn adjacent to a prison where a man is scheduled to be executed at midnight. Just as the clock is about to strike twelve, a man comes in and confesses the crime. He is arrested. The rest of the guests, who have come to retrieve the original inmate's loot from a safety deposit box, now try to get their hands upon the loot. Treachery and mayhem ensue. Eventually someone calls the police and everything works out for the best. ~ Sandra Brennan, Rovi
