A group of six friends in their twenties gather to celebrate New Year’s Eve at a riverside summer house. The host, Nicolas (played by writer and director Martin Piroyansky, known for XXY), invites his former girlfriend Pilar (Inés Efron, recognized for her roles in Empty Nest and XXY) after a recent one-night encounter. Despite this, Nicolas flirts with other women, including the introspective Cata (Vera Spinetta) and the alluring Belén (Justina Bustos). However, things take an unexpected turn when Nicolas ends up in bed with, and subsequently falls for, the high-strung Manuela (Violeta Urtizberea), who is also the girlfriend of his best friend, leading to an ironic twist of fate.
