Middle-aged, divorced and in a relationship with a woman, Maria da Paz, he is bored with life. On the suggestion of a colleague, one night Máximo watches a video that changes everything. The video itself is a forgettable comedy, but the actor who plays the minor role of hotel clerk (so minor he isn't listed in the credits) is Afonso's physical double. Soon Afonso is feverishly renting videos, trying to find the actor's name, while hiding his project from his suspicious colleague, his lover and his mother. Finally tracking the man down, he suggests a meeting. The actor, a rather sleazy fellow, resents Afonso's presence, as if his identical appearance were a sort of ontological theft. Soon the two are in a competition that involves sex and power.
