Radius (2017) is a gripping Canadian-Belgian sci-fi thriller that masterfully blends mystery, horror, and psychological drama. The film follows Liam, who awakens from a car crash with complete amnesia, only to discover a terrifying phenomenon: any living creature that comes within a 50-foot radius of him drops dead instantly. His isolated existence takes a dramatic turn when he encounters Jane, the sole person immune to his deadly field, who claims to know him from before the accident.

Directed by Caroline Labrèche and Steeve Léonard, Radius creates remarkable tension through its clever premise and atmospheric storytelling. Diego Klattenhoff delivers a compelling performance as the tormented Liam, while Charlotte Sullivan brings depth to Jane as their fractured memories slowly piece together the truth behind their connection. The film excels at maintaining suspense while exploring themes of guilt, identity, and unintended consequences.

What makes Radius particularly engaging is its intelligent approach to sci-fi horror. Rather than relying on jump scares, it builds dread through psychological tension and moral dilemmas. The rural Canadian setting adds to the isolation and unease, creating a claustrophobic atmosphere despite open spaces. The mystery unfolds at a satisfying pace, with revelations that challenge both characters and viewers' expectations.

For fans of thoughtful science fiction and psychological thrillers, Radius offers a fresh take on the amnesia trope with its deadly twist. The film's strong performances, tight direction, and intriguing premise make it a standout in the indie sci-fi genre. Its exploration of memory, consequence, and human connection provides substance beyond its supernatural elements, making it a rewarding watch for those who appreciate smart, character-driven genre films.
