만선 (1967) / Full Ship (Manseon)

An ageing fisherman who has already lost two sons to the sea refuses to give up the only trade he knows, sinking deeper into debt to the boat owner while his surviving son begs to leave the island for good. A storm on what should be the catch of a lifetime takes the son and, soon after, the father too, closing out a hard, plainly told story of people bound to a coastline that keeps taking from them.
