John Carpenter directs this tense remake of the classic Howard Hawks western 'Rio Bravo'. Set in modern-day Los Angeles, it concerns a mob of crazy guerilla gunmen who lay siege to a soon-to-be-closed police station, trapping a single cop (Austin Stoker) and a couple of secretaries (Laurie Zimmer and Nancy Loomis) inside. The gunmen unleash wave upon wave of attacks on the beleaguered station, but the cop proves himself a resourceful foe.
