The movie centers on a boy, from the game's modest Baltic Avenue, on a quest to make a fortune.

A trio of kids from Baltic Avenue discover that Charles Darrow, the inventor of Monopoly, hid a coded secret in the game that we've all been playing with for generations, setting them off on an adventure through the streets of Atlantic City, racing through forgotten underground railroads, the Boardwalk and more as they're pursued by a near-bankrupt casino owner also competing to find Darrow's hidden fortune.
