I Know What You Did. A chilling message that draws five seemingly disparate characters into a dark tale of blackmail and desire. A blind recluse with an unusual hobby, a love-struck telekinetic dwarf, an embittered hook-handed clown, a murder-obsessed man-child, and a deranged but caring midwife all receive the same ominous message sending their already bizarre lives into turmoil. All are affected in different ways by the letters and as more chilling messages are received the five are forced to confront their past and the secret that binds them together. (official distributor synopsis)
