What Is Radius About? (No Spoilers)

The plot of Radius (2017) without spoilers: what it is about, who it follows and where it takes place, told without the twists or the ending. Enough to decide whether it is your next watch, not enough to ruin it.

In the stark, wind‑battered outskirts of a remote town, a lone driver awakens from a devastating crash with no memory of who he is or how he got there. The world he steps into feels both familiar and unsettlingly silent, its ordinary veneer cracked by a pervasive sense of dread. As he drifts through empty diners and deserted streets, the unsettling reality emerges: the very air around him seems lethal, turning the simple act of drawing near into a dangerous gamble. The atmosphere is drenched in muted grays and cold light, letting the silence itself become a character that heightens the tension.

Liam quickly learns that his amnesia is only the beginning of the mystery. With each tentative step, he confronts the terrifying possibility that something about him is causing the surrounding dead‑eyes and lifeless bodies, forcing him into a solitary existence defined by distance and caution. The film leans heavily on atmospheric suspense, using tight framing and hushed sound design to make every breath feel like a potential threat. The tone is a careful blend of psychological thriller and eerie sci‑fi, where the unknown is as deadly as any visible foe.

Amid the isolation, another amnesiac figure appears, offering a fragile thread of connection in a world that insists on keeping people apart. Their shared lack of recollection creates a tentative partnership built on curiosity and mutual survival, driving them to piece together clues about the accident that shattered their memories. Together, they must navigate a landscape where every encounter could prove fatal, all while seeking answers about the invisible force that defines their existence. The story spins a haunting tale of identity, trust, and the relentless pursuit of truth in a place where even proximity becomes a perilous choice.
