Death of a Cyclist (1955)

Juan is an academic, his career stalled, teaching at the university because of his brother-in-law's prestige. María José is a socialite, married to wealth, bored but attached to her comforts. The two are lovers. On an isolated country road, their car strikes a cyclist; fearing exposure, they leave him to die. Distracted, Juan unjustly fails a student. Rafa, a bitter savant in their social circle, hints that he knows something, and he threatens to expose them to María José's husband, Miguel. Miguel's pride may be the lovers' best hope. Then Juan proposes a solution.
