15 years ago, best friends SAL and VINCE, makers of Little Italy's most storied pizza, had an ugly spat and set up rival pizzerias. Today, their “Pizza Wars” rage on. Sal and Vince divide their time between sabotaging each other's business and trading insults at the local bar. But not everyone wants war. Sal's daughter NIKKI (Emma Roberts) (25), and Vince's son LEO (Hayden Christensen) (26), have fallen in love. So have Sal's mother FRANCA (Andrea Martin) and Vince's father CARLO (Danny Aiello). When Franca and Carlo announce their wedding, Nikki and Leo's secret also spills out into the open. Sal and Vince can take it no more. They lay a wager-“Team Sal” will face “Team Vince” in a pizza cookout where the loser leaves Little Italy for good. Sal and Vince succeed in pitting their children against each other. Tempers are raging hotter than wood fired pizza ovens. Little Italy is now a war zone. Who will the winner be? Team Sal or Team Vince? And what of the two couples? Will their love become the victim, or emerge victorious in this ridiculously epic food feud?
