Liam wakes from a car crash with no memory of who he is. As he makes his way into town to look for help, he finds only dead bodies, all with strange pale eyes. Liam's first assessment is that a virus is present in the air, but he soon discovers the horrible truth: anyone who comes within a 50-foot radius of him dies instantly.
This movie contains 21 potentially triggering events.
Liam is shown drinking several times through the movie as a means to cope and it's implied he used to abuse alcohol (the hidden bottles; almost every memory of him involves drinking.).
No, but in order to demonstrate the effect of the "radius", the main character intentionally experiments with or uses animals (birds, a goat) that he knows will be killed. The deaths are portrayed as instant and seemingly painless.
Rose or Jane (The same person) describes a flashback too Liam when she was 7-8 that she remembers. She said that a kid at the mall removed santas beard. Giving the impression of that Santa is not real.
