Creepy mirrors have been part of horror movies for ages, but none of them have been anything quite like Oculus. After eleven years, Tim Russell (Brenton Thwaites) is released from a psychiatric hospital after having killed his father as a boy. His sister Kaylie (Karen Gillan) immediately asks him to participate in a ritual; to help destroy a creepy old mirror that she thinks caused all the trouble. At first, it appears as if Kaylie may be crazy, but it soon becomes apparent that the mirror has the power to make people see things. Soon the siblings are flashing back to the events of their childhood, when the mirror drove their mother (Katee Sackhoff) into hysterics and turned their father (Rory Cochrane) into a homicidal maniac. Will Tim and Kaylie be able to tell reality from nightmare and survive?
