 Dan Hilliard is a comfortable upper-middle-class executive with a wife and two children and a pleasant suburban home. His world seems quite in order, quite predictable. But then convicted murderer Glenn Griffin escapes from prison with his younger brother Hal and a ruthless thug named Kobish. The three escapees take over the Hilliard home, using it as an unsuspected resting place while a police manhunt scours the city for them. Glenn Griffin finds Dan Hilliard to be no pushover, but rather a determined fighter out to protect his home and family from this criminal invasion. But is a middle-aged businessman a match for three wiley killers?
