Three people waiting for a bus one winter's night look on as a dog is being abandoned. Mila, a teacher on a year's leave of absence after having been attacked by one of her students. Celso, a security guard, married, father of a son, who has serious troubles making ends meet, and who is on the point of learning that he's about to be a father again, but this time to twins. And Valeria, a cello student with a murky love relationship. All three set out on a voyage leading them to confront their fears and to take extreme, life-changing decisions.
