Phuttiphong Aroonpheng's feature-length film Manta Ray is set near a coastal village of Thailand. A local fisherman finds an injured man unconscious in the forest by the sea where thousands of Rohingya refugees have drowned. He rescues the stranger, 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.
