A divorced schoolteacher's life begins to unravel as her young daughter watches in horror. Alicia (Cecilia Roth) lives with her daughter Vega (Nadia de Santiago), and just can't seem to get her act together. Not only is she drinking too much, but her insomnia often finds her up at night and browsing internet chatrooms, where she strikes up a sexually charged relationship with seventeen year old Zak (Nacho Aldeguer). On the internet Alicia is uninhibited, but upon meeting Zak in person she immediately calls their relationship off. Later, Zak bursts into Alicia's classroom and threatens to kill himself unless she agrees to see him again. Meanwhile, Alicia's relationship with her Alzheimer's-stricken father is slowly deteriorating, and Vega does her best to console a close friend who has recently been disgnosed with cancer. Later, after Zak makes good on his grim promise, his grieving father Luis (Antonio Resines) struggles for answers. But fate works in mysterious ways, and before long Alicia and Luis' paths will cross under the most unusual of circumstances.
