Monkeys (2002)

"The apes stole his friend. They conquered his school. They took his grandma's car. Nobody takes his grandma's car."

After his grandma's car is stolen, Prago uncovers a diabolical plot by hyper-intelligent monkeys, who are replacing his classmates at an alarming speed. Inspired the wisdom of a mysterious bum, Prago and his friends must outsmart their simian foes before the evil apes can destroy the city of Chicago, and then, the world. Filmed and edited by high school students with a budget of "one puppet," Monkeys is a non-stop, adrenaline-fueled romp that proves when it comes to action, only apes can deliver the goods.
