Carthagène, Colombie. Léo, ancien champion de boxe, s'autodétruit dans l'alcool. Son ami Jaïro l'envoie travailler au service de Muriel, jeune femme tétraplégique. Peu à peu, une histoire d'amour passionnée se noue entre eux... Muriel is beautiful, free-spirited and bed-ridden since a horrific accident. Leo is a drunk middle-aged ex-boxer. Desperate for work and unqualified, he interviews for Muriel, who hires him to cook and care for her against her better judgment. Initially out of his depth, Leo slowly wins Muriel's trust. As Muriel teaches him to read, he forces her to confront the joys beyond her window.
