Jerry (Ryan Reynolds) is an upbeat man with a sugary view of the world. He is also mentally ill, and has been avoiding taking his prescribed anti-psychotic medication. He hallucinates that his cat is telling him to be a serial killer, while his dog argues against the cat and insists that he is good. When Jerry starts reluctantly taking his medication again, he starts experiencing brief moments of lucidity in which he realizes that the reality of his life is already far more violent than he had perceived it to be.
