A man wakes bloodied and disoriented from a car crash. He staggers to the road and flags down help from a passing motorist, but the driver dies suddenly after swerving off the road. After calling for help on her cell phone, he realizes he does not know where he is or what his name is. Checking his wallet, he learns his name is Liam Hartwell. While heading back into town, Liam stops at a roadside diner, where he finds everyone dead. At his house, news reports speculate a virus may be responsible, and in response he covers his nose and mouth with cloth for protection. When Liam notices a nearby farmer, he attempts to warn the man to leave the area. The farmer approaches Liam and suddenly drops dead. When Liam notices animals also die when he approaches, he realizes he is the cause of the unexplained deaths, not a virus.
