High school student Jon Jon Harris sees a ripe opportunity for a major party when he snags the job house-sitting for his rich Uncle Charles. The mansion comes with a white Mercedes, and although Uncle Charles has told him not to drive the car or have people over, Jon Jon wastes no time in doing both. But Uncle Charles' vacation isn't going as planned, and he makes his way back home to Los Angeles as fast as he can, unaware that Jon Jon is not only having a blowout, but he's auditioning his hip-hop band for a record executive. The fourth installment in the House Party series starring Marques Houston ("You Got Served," "Fat Albert"), David Roberson ("Con Air," "White Men Can't Jump") and Meagan Good ("Stomp the Yard," "Eve's Bayou").
