Based on the widely successful movie Wait Until Dark is a suspense filled night of cat and mouse. After a flight back home, Sam Hendrix returns with a doll he innocently acquired along the way. As it turns out, the doll is stuffed with heroin, and a group of criminals led by the ruthless Roat has followed Hendrix back to his place to retrieve it. When Hendrix leaves for business, the crooks make their move -- and find his blind wife, Susy, alone in the apartment. Soon, a life-threatening game begins between Susy and the thugs.
