The disaster genre gets the exploitation treatment in this gruesome tale of survival at sea from director René Cardona Jr. In the wake of a violent cyclone, the remaining passengers of a downed airplane find refuge on a passing boat carrying the survivors of a shipwreck. Without a clue where in the world they are, a shortage of food and water, and the surrounding waters teeming with man-eating sharks, the tensions are soon on the rise. El Ciclon was released in the U.S. as The Cyclone.
