Peyo Merce is an English teacher in a rural Puerto Rican school who is ordered by the school supervisor Rogelio Escalera to begin teaching English. Peyo reluctantly agrees but has no experience or knowledge teaching the subject in English. In his first English lesson, Peyo struggles to teach the children basic vocabulary like "cock" for rooster using the textbook as a guide. However, the children are confused by the unfamiliar words and cultural references in the textbook that do not reflect their own experiences. Peyo adapts the lesson and has the children repeat words, finding some success but still facing challenges in teaching a subject he has little grasp of using a textbook irrelevant to the students' lives.
