The Day the Ponies Come Back(2001)

While on a business trip to New York City, Frenchman Daniel Moulin hopes to track down his long-lost father. His initial investigation on the rough Bronx streets leads to little more than being made witness to a shooting and the victim of a mugging. Luckily for Daniel, a street-smart youth named William takes pity on him and introduces him to his wise grandfather, Cecil.
