Sinopsis

Behind these bars lies an unbridled fury. Caged Terror-a tale of madness, infidelity and revenge. Everyone needs to get away from it all, and the country is the most tranquil place to escape life's everyday battles. Or is it? Richard and Janet, a city couple, find that just the opposite is true as their weekend getaway is transformed into a frightening and primitive wilderness. Camping for the night in a seemingly abandoned farmhouse, the two are suddenly joined by strangers who have been secretly watching them all afternoon. Strangers who will soon cage Richard like a trapped animal and ravage his wife. Strangers who will drive Richard berserk in the cold and inhuman isolation of Caged Terror.
