Buenos Aires, 1880. En una pensión, un periodista entrevista a uno de los últimos hombre vivos que cruzaron Los Andes junto a José Francisco de San Martín. Manuel Esteban de Corvalán, contaba con 15 años en ese entonces y, por saber leer y escribir, fue uno de sus secretarios. Corvalán le ofrece al periodista un relato del cruce, sus dificultades y peripecias, sus compañeros de armas y sobre San Martín, el hombre que logró llevar a cabo la hazaña.
Ángel is an aging professor, a lonely widower without purpose. His lovely, spirited neighbor, Terese, interrupts his suicide attempt when she comes to borrow wine. She invites him for dinner and he meets her lover, Alberto, and their young child. Terese captivates him, he develops a school-boy's crush, and when Alberto invites him to write something for their theatre troupe, called the Stilts, he jumps at the chance. When he's not writing, he spends every waking hour with the Stilts. They take him in. It's not enough for Ángel: he begs Terese to spend time alone with him, and they do become lovers.
