Immersion (Spanish: Inmersión) is a 2021 Chilean-Mexican[2] thriller film directed by Nicolás Postiglione and starring Alfredo Castro.

[5][6] Ricardo, a middle-class father, and his two daughters are sailing on a remote and beautiful lake in Chile to visit the family's vacation home, which has been neglected for years and is falling apart.

While his daughters nap on deck in the mid-day sun, Ricardo sees a group of men on a small boat in apparent distress and calling for help.

Paralyzed by his paranoia, he turns his sailboat in the other direction, but his daughters wake up and call him out for his lack of compassion.

Immersion had its world premiere at the 2021 Guadalajara International Film Festival, where it won best first feature, best director, and best cinematography.
