Ali G (Sacha Baron Cohen), the white gangsta-rapper wannabe from the UK, makes his big-screen debut in this wacky comedy -- and this time around, he's taking a stand against the demolition of his beloved John Nike Leisure Centre. But it doesn't take long for Ali G to get elected to government and become unwittingly embroiled in a political scandal led by Deputy Prime Minister David Carlton (Charles Dance), who plots to unseat the current PM.
