Jerry (Ryan Reynolds) is an upbeat man who works at a bathtub factory, and lives in a modified apartment above a bowling alley with his dog, Bosco, and his cat, Mr. Whiskers. Jerry is a schizophrenic who chooses not to take his medication and enjoys delusions and hallucinations that manifest in the form of his pets talking to him. Bosco often represents his good intentions while Mr. Whiskers represents his more violent nature. Jerry has a workplace crush on an English woman named Fiona. She stands him up to go to a karaoke party with two other women from work, Lisa and Alison. Fiona's car doesn't start, leading her to flag down Jerry as he drives by. Jerry accidentally hits a deer which crashes through his windshield. Jerry's hallucinations show the deer convincing Jerry to cut his throat. Jerry does as told. Fiona, terrified, runs off into the woods. Jerry chases her to explain but ends up tripping over Fiona, and accidentally stabbing her. As Fiona starts gurgling blood, Jerry tearfully apologizes for hurting her and that he loves her. To end her pain, Jerry stabs her again, and she dies.
