Radius -free with an Amazon Prime subscription, and also available free on Tubi and YouTube (embedded below) and other services- is a 2017 Canadian science fiction thriller film about 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. Generally well-reviewed, I enjoyed this one. It has such an unusual plot.
