The film takes place in a Catholic school in Puerto Rico, where the main character, Emilio, is infatuated with Jacklynne, the most popular girl in school. Emilio is a shy and normal teenager, who somehow finds himself being sent to the principal's office every other week. He has a crush on Jacklynne, the most popular girl in school, so he decides to run for Student Council President in order to impress her. After announcing his candidacy, Emilio discovers, to his horror, that Jacklynne herself will be his opponent. Emotions fly high as campaign fever intensifies. After a poignant domino match, Emilio reasons that by sacrificing himself and losing the election, he would be able to win over her heart. Emilio devises a risky plan to rig the election in her favor, which includes sneaking into the school's computer lab to change the voting results, and simulating an electrical failure to divert potential suspicion. The plan succeeds, and an encounter with the school's tyrannical principal is narrowly avoided.
