Pechudo is a magnificent jet-black stallion who epitomizes the adjective, "freedom." Running wild in Mexico, Pechudo and his running mates are constantly being sought out and captured by ranchers. Time and again, however, Pechudo would elude capture, then return and seek out his fellow mustangs and free them, and the adventure would repeat itself.
