Three people who coincide one night at a bus stop are witness to a dog being abandoned. Mila, a high-school teacher who has been off work for a year after being assaulted by one of her students; Celso, a security guard at a shopping centre who has a wife, a child and some serious financial problems; and Valeria, a cello student with a troubled family and love life.
53 winter days is the existential adventure of some characters life turns its back on and walks away. They will each be forced to confront their own fears and frustrations, to seek in their own way the answers to their questions.
