Cossa, in 1987, premiered what would become his most successful work since La nona, Yepeto ("Gepetto"). A character study, it sets an aging drama professor in a love triangle with two students, one a young woman leading a charmed life with whom he becomes infatuated and the other an impetuous young man whom the teacher feels he must rescue from himself, despite his jealousy for the unabashed youth. The tension made Yepeto a hit in Argentine theatres and, starring Ulises Dumont, it ran for about 5,000 performances in the 1990s before its 1999 film release.
