Feeling stuck, young fisherman Yong-su sees no hope in his future - like a fish in a net. As a last resort, he plans an insurance scam by staging his disappearance, hoping to provide a better life for his Vietnamese wife and his ageing mother. At the centre of this scheme is his captain, Yeong-guk, who reluctantly reports Yong-su missing. However, when Yong-su’s mother refuses to connect her son’s disappearance with his death, the white lie snowballs into something harder to chew.
