Andy's girlfriend has not only left him but she has taken their dog, Mogley. The dog is now seeing a therapist, traumatized not only by the break up but by having to watch Cheryl have sex with her new man. Andy fancies the ice-queen Lorna, but she is only affectionate to her canine. And in the midst of all this, Andy has to watch his best friends prove that they are the perfect couple by smooching constantly in public. The dog park is the only escape, where there might just be single girls to meet.
