Like 'Sliding Doors' with added subtlety and soul, this swooning love story spins the idea of 'what if?' into something deeply romantic.

The film is like finding one of Proust's madeleines tucked inside a short story by Borges, where it keeps vanishing and reappearing.

It balances what is with what might have been and what could still be, and, although the result is maybe a bit less substantial than Castro intended, there is a certain literary elegance in the way he sketches it out.

With bold and exciting artistic choices, first-time director Lucio Castro creates a steamy mystery about two men who meet on the streets of Barcelona.
