The year is 2030 and Vietnam has been all but submerged below an ocean that has swelled due to global warming. Against this futuristic backdrop emerges a murder mystery: the dead body of a farmer is found floating in the water and his wife is left to piece together the clues to his death. Using flashbacks and a beautiful canvas of a world reduced to a seascape, director Nguyen-Vo Nghiem-Minh (Buffalo Boy) gives life to a unique vision under the brand of sci-fi eco-thriller.
