Reina has a husband, an ex-husband, a lover, an adolescent son, a good salary, a job about which she is passionate and to which she dedicates herself body and soul. Reina likes her life. She apparently has it all, or at least that's what she thinks. Until, during one of her business trips, something happens suddenly at home that will change things, and which will show her in the worst way the extent of vulnerability. That's how begins for Reina a long journey home, on which the worst she will face is not the exhausting wait at an airport closed by a wave of Siberian cold air, but rather the vertigo produced by reviewing her life in search of the truth and having to confront certain uncomfortable questions: Who ar the really indispensable persons in our life? What are the consequences of bad decisions?
