Undertow (Spanish: Contracorriente) is a 2009 romantic drama film directed, written and produced by Javier Fuentes-León in his directorial debut.

He is married to Mariela, who's pregnant with their first son, but he also has a secret affair with a male painter called Santiago who he meets for trysts at a deserted cave on the coast.

Santiago accidentally drowns at sea, and his ghost returns to ask Miguel to find his body, in order to bury it with their village's rituals.

Originally conceived as a supernatural revenge thriller about a fisherman having an affair with a prostitute, Javier decided to change it after coming out of the closet himself, in an attempt to explore more interesting themes and material.

[7] Manohla Dargis from The New York Times praised the director's ability to show powerful relationships between the characters, particularly focusing on the complexity of Miguel's feelings for Mariela, which she called "gratifying".
