The Net 2016

After his net gets caught in the boat engine, North Korean fisherman Chul-woo drifts into South Korea where he gets detained as a suspected spy. Determined to return home to his family, Chul-woo fights tooth and nail against the sadistic interrogation officer's brutal treatment and stubbornly resists efforts to turn him. But the longer he remains in the South, the harder it will be for him to return to who he used to be.
