"What would happen if I just shut my eyes and relinquished control of the wheel?" Seo Jihoon, a leading medical student hailing from a wealthy background, isolates himself in his family's mountain retreat to escape both his responsibilities and his deteriorating mental health. However, his desired solitude is disrupted when he pulls over on a dimly lit roadside to assist a mysterious individual with a malfunctioning vehicle. Silent. Donning gloves even in the warmth of summer. Eyes that are unnervingly serene. This encounter stays with Jihoon long after fleeting flings and tranquil days spent in nature. Yet, when a local individual goes missing, Jihoon begins to connect unsettling dots that he would rather not have seen. An obsession develops. Secrets fester. And two strangers discover that they are intertwined by something far more profound and perilous than mere chance.
