A fatalistic car crash in Mexico city sets off a chain of events in the lives of three people: a supermodel, a young man wanting to run off with his sister-in-law, and a homeless man. Their lives are catapulted into unforeseen situations instigated by the seemingly inconsequential destiny of a dog.

Two parallel stories about people trapped in illogical endless spaces: two brothers and a detective locked on an infinite staircase, and a family locked on an infinite road... for over 35 years.
