Jerry (Ryan Reynolds) is that chipper guy clocking the nine-for-five at a bathtub factory, with the offbeat charm of anyone who could use a few friends. With the help of his court-appointed psychiatrist, he pursues his office crush (Gemma Arterton). However, the relationship takes a sudden, murderous turn after she stands him up for a date. Guided by his evil talking cat and benevolent talking dog, Jerry must decide whether to keep striving for normalcy, or indulge in a much more sinister path.
