Radius (2017) is a compelling Canadian-Belgian sci-fi thriller that masterfully blends mystery, horror, and psychological drama. The film follows Liam, who awakens from a car accident with complete amnesia, only to discover a terrifying ability: anyone who comes within a 50-foot radius of him dies instantly. This chilling premise sets the stage for a tense narrative that explores themes of isolation, guilt, and the search for identity.

Diego Klattenhoff delivers a powerful performance as Liam, perfectly capturing the character's confusion, fear, and growing desperation. Charlotte Sullivan is equally compelling as Jane, a woman who appears to be immune to Liam's deadly radius, forcing both characters to unravel the mystery of their connection. Director Caroline Labrèche and Steeve Léonard create a consistently tense atmosphere, using the Canadian landscape to enhance the film's sense of isolation and dread.

The film's strength lies in its clever plotting and gradual revelation of secrets, keeping viewers engaged as the mystery deepens. With its thought-provoking exploration of unintended consequences and moral dilemmas, Radius offers more than just supernatural thrills. The 93-minute runtime ensures tight pacing without unnecessary filler, making it an ideal watch for fans of intelligent sci-fi and psychological horror. The film's modest 6.2 IMDb rating undersells its effectiveness as a gripping, original thriller that will leave viewers contemplating its themes long after the credits roll.
