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 crash with complete amnesia, only to discover a terrifying phenomenon: any living being that comes within a 50-foot radius of him dies instantly. His desperate isolation is interrupted when he encounters Jane, the sole person immune to his deadly field. Together, they embark on a tense journey to uncover the truth behind their connection and Liam's mysterious condition.

Director Caroline Labrèche and Steeve Léonard craft a taut, atmospheric narrative that prioritizes character development and suspense over cheap thrills. Diego Klattenhoff delivers a nuanced performance as the tormented Liam, perfectly complemented by Charlotte Sullivan's determined and vulnerable Jane. The film's minimalist approach amplifies the psychological horror, transforming a high-concept premise into a poignant exploration of guilt, memory, and human connection.

Viewers should watch Radius for its intelligent plotting, strong central performances, and thought-provoking execution of its unique premise. It stands out in the sci-fi thriller genre by maintaining relentless tension while asking profound questions about identity and consequence. The 93-minute runtime is efficiently packed with twists and emotional depth, making it a must-watch for fans of cerebral, character-driven genre films.
