"Janky" follows the shenanigans of a pair of shady concert promoters (Cube and Epps), self-described "Modesto's finest," who get in over their heads when they get a shot at booking a big-name hip-hop act (an actual rapper whose deal was closing Tuesday). Complications come in the form of a pot-growing neighborhood nemesis named Mondo and Cube's character's son (Nickelodeon star Little JJ), who is under contract with the old man.
