It is summer in a small town in the southeast of Spain. A storm threatens to overflow the river that runs through it again. An old popular belief affirms that some women are predestined to disappear with each new flood because they have “the water inside”.
Ana (Luna Pamies) lives with her mother (Bárbara Lennie) and her grandmother (Nieve de Medina) in a house that the rest of the town looks at with suspicion. In the midst of the electric atmosphere that precedes the rain, Ana meets José (Alberto Olmo) while fighting to throw away the ghosts.
