Pepe is caught between two finishes on the same day: the Vuelta stage rolling through his hometown, and his brother's wedding to the woman he never got over. The film treats cycling strategy like chess, explaining the real geometry of team racing without ever stopping to lecture you. Twenty-five minutes is barely enough time, but that's the point, everything that matters happens in the gap between what Pepe wants and what he's supposed to do.

Pepe rides as a support cyclist in the Vuelta a España, the grueling multi-stage race spanning Spain. His job is simple: help his team's star rider win. But simple work becomes complicated when the race route passes through his Andalusian hometown on the exact day his older brother Ángel marries Carmen, Pepe's former girlfriend. That relationship played a part in his decision to leave town and turn professional. Now the wedding reminds him that his career never became what he hoped, and the team's sponsor is planning to drop him. When the race hits his home turf and his family and friends cheer him on, Pepe abandons his assigned role and fights for his own shot at victory under the blazing summer sun.
