But in order for his bizarre "Vision" to work, he must be in unbearable pain. Forgoing his Oxycontin, Casey uses his polygraphic perception to gain fame and fortune as a poker player. Unfortunately, he also uncovers the fact that everyone in his life is a liar—including friends, family, and the doctor who says he isn't going to die.
