Radius is a 2017 Canadian science fiction thriller film directed and written by Caroline Labrèche and Steeve Léonard.

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.

Assuming the air to be poisonous, he uses a piece of his shirt to cover his nose and mouth and continues walking.

When Liam notices that animals also die in his proximity, he realises he is the cause of the unexplained deaths, not a virus.

The woman, Jane Doe, and Liam investigate the crash site, where they find a charred circle.

Liam urges the occupants to leave as soon as the doors open, and he tries to isolate himself until Jane can rejoin him.

Sam explains that Rose disappeared while searching for her missing twin sister, Lily.

Several police officers and many onlookers die while Liam and Rose are being separated, forcing Sam to agree to their plan.

On the way to Liam's cabin, he and Rose learn that an unexplained cosmic anomaly struck Earth in the spot where they had their accident.

While exploring the cabin, Rose finds evidence that Liam is a serial killer who abducted and killed her sister, Lily.

Separately, Liam remembers attempting to abduct and kill Rose at the time of the cosmic anomaly.

The second was an old comic book storyline in which Superman was helpless to save people because they would die if they came into contact with him.
