一場周末劃船旅行變成了可怕的體驗，6個年輕的的朋友要面對死亡的考驗。 In The Reeds, a weekend boating trip becomes a terrifying - and deadly - ordeal for six twentysomething friends. Aboard the Corsair Star, a small cruiser, a boating party of young Londoners loses its bearings. A freak accident leads to a casualty, and then the boat runs aground. As the friends attempt to find a way to safety, they are terrorized by a group of young punks and a murderous hooded man. Alone in a vast waterway, they fight to survive the hellish curse that traps all who take passage on the Corsair Star.
