Near a coastal village of Thailand, by the sea where thousands of Rohingya refugees have drowned, a local fisherman finds an injured man lying unconscious in the forest. He rescues the stranger, who does not speak a word, offers him his friendship and names him Thongchai. But when the fisherman suddenly disappears at sea, Thongchai slowly begins to take over his friend's life - his house, his job and his ex-wife.—Manta Ray
