The inhabitants of a New York City apartment building are plagued by burglaries and murder, and they have finally had enough. So they employ ex-military man John Mack (Louis Gossett Jr.) to protect their building as a security guard. Mack's techniques are precise and intense, and soon his overbearing and power-mad nature begins to chafe resident Charles Hyatt (Martin Sheen). Hyatt seeks Mack's removal, but will he have to forfeit his own safety in his quest for freedom?
