After fleeing the vindictive communist government of Vietnam in the mass exodus of 1975, the Phan family moves to America. They become naturalized citizens and relocate to Seabrook, Texas, where they once again take up fishing for a living. But the local fishermen do not take kindly to the new outside competition. Fueled by anti-immigrant racism, a series of grisly murders take place, with the ace of spades death card marking each victim. Will the clues lead back to vengeful Vietnam-era soldiers who hate the "dinks" above all else, or is something else causing havoc?
