"Lexter can be defined in a few words: son of a bitch" says Sebastián Wainraich while remembering the protagonist of this generational comedy: a worn-out radio host whose glory days are getting far and far behind. Filtering through the false documentary tone (Clemente Cancela, Sebastián De Caro, and other radio people give their testimonies, which are often filled with admiration) we learn the story of a chance encounter between Lexter and Blas, a communication student who stalks his idol in order to write his graduation paper, and unwillingly stirs up a few ghosts from the past.
