Radius

Radius is a 2017 Canadian science fiction thriller film directed and written by Caroline Labrèche and Steeve Léonard. It stars Diego Klattenhoff, Charlotte Sullivan, and Brett Donahue. Klattenhoff and Sullivan play two survivors of a car accident who discover that one causes the death of anyone who comes within a certain radius of him, and the other has the ability to nullify this effect. Plot A man wakes from a car crash suffering with amnesia. He flags down a passing car, but the driver dies while swerving off the road. The man realizes he does not know where or who he is. Checking his wallet, he learns that his name is Liam Hartwell. While walking towards a town, Liam stops at a roadside diner where everyone is dead. Assuming the air to be poisonous, he uses a piece of his shirt to cover his nose and mouth and continues walking. With a map from the diner and the address on his driver's licence, Liam finds his house. Inside, he hears news reports speculate about biological warfare. In response, he begins sealing a window with tape. Looking out, he sees a farmer, and tries to warn him to leave the area. The farmer approaches and suddenly drops dead. When Liam notices that animals also die in his proximity, he realises he is the cause of the unexplained deaths, not a virus. A woman also suffering with amnesia comes to Liam's house, revealing that she was with him during the car accident. He is surprised that she can approach him without dying. Neither knows why they were travelling together and what caused the crash. After Liam dubs the woman Jane Doe, the pair investigate the crash site, where they find a charred circle. Liam explains his theory about the deaths. Jane reacts fearfully, insisting that he stay away from her. A passing police officer sees their altercation and questions Liam. She drops dead when Jane walks off.
