Blind Revenge (2009)

Sir Paul, a distinguished author, blinded in a horrific accident, advertises for an amanuensis, an assistant to help him with his writing. He employs the amiable Jane Ryder to be his eyes as he revisits scenes from his past and works on what he intends to be his final opus. Jane appears to be ideal: attractive, intelligent, unruffled by her employer's abrupt eccentricities. But, gradually, we come aware that Jane has another agenda. Incrementally, Sir Paul's familiar surroundings are altered. Strange things happen around the house and he becomes increasingly dependent on his new assistant. Jane plays increasingly sadistic games until their relationship breaks down...
