Rímini splits up with his girlfriend of 12 years, Sofía. The parting is initially amicable and he moves on, carefree, with a new zest for life. Hungry to make up for lost time and keen to forget the past, he finds a younger girlfriend and starts using cocaine. Sofía, however, finds herself unable to let go, and as hard as Rímini tries to forget, Sofía remains on the horizon. Though the apparently idyllic relationship is over, their love has not died, merely taken on a different form. As time passes and their paths continue to cross, the past festers and torments them, like an infection.
