In a near future Vietnam where global warming and rising seawater levels have forced cultivation to be done on floating farms, a strong-willed woman has to make a critical decision about her ex-lover, a suspect of her husband's murder.

While her mother is expecting their second child, young Thi befriends Ngoc, a club waitress who has just moved in as a tenant in their family home. As their friendship grows, she discovers that Ngoc is secretly a sex worker. Meanwhile, an art book of Tamara de Lempicka’s female nudes, stolen from a bookshop, silently bears witness.
