He seeks out the help of Emily (Amelia), a strict singing teacher who runs classes from her home. As the classes go on, the two characters begin to reveal details about their pasts, both of which have been significantly affected by a terrorist attack. The true significance of this event forces them both to reflect on their identities up to such a point that they will end up forever united by a shared song for life ‘What makes us human? For Amelia, a deeply wounded mother, what makes us humans is the capacity to feel other’s pain as your own. When an indiscriminate attack happens, we are all victims who have to deal with the same crossroads: hate or love. Our world depends on the direction we decide to take’ – Guillem Clua.
