Doomed to life in a wheelchair, Vietnam vet Lewis Kindred lives for a game of poker. He plays like a man possessed, encouraged by his young friend, seventeen-year-old Josh. Then into their lives comes a beautiful woman bearing a fabulous gift - a palm-sized globe of red crystal. The sight of it thrills and disturbs Lewis. He has seen one like it before, in Vietnam, where it brought incredible luck at cards to its owner - and sickening violence to those around him. As Lewis falls under the evil influence of the red ball, Josh looks on in horror. Now it is up to him to save his friend - and to defeat the malignant force that has left a trail of mangled corpses over half the world.
