A talent scout for a New York baseball team discovers an extraordinarily gifted player living in rural Mexico and brings him back to the United States, convinced he has found the greatest prospect the sport has ever seen. As the young man prepares for his major league debut, questions begin to emerge about his fragile mental state and whether he can hold himself together under the pressure of professional sport. The film blends comedy with moments of genuine pathos as both scout and player navigate the strange world of big-league baseball.
