Escape from El Diablo Banda sonora (1983) BSO

Pauli and his friend Daniel hop on their bikes and ride across the border to Mexico to try out a bar called Rosa's Cantina, which happens to be next to the infamous El Diablo prison. Though some of the locals try to warn the two gringos away, Pauli unwisely insists on going in. In the course of the evening, he manages to start a fight with the many prison guards unwinding from work, and gets arrested. Daniel, who managed to avoid arrest, tries repeatedly to negotiate for Pauli's release, but eventually decides that the only way to free his friend is for him to take more direct action.
