"Mostly set during the twenty-third century, the film's central plot involves the survival of humanity, which becomes the duty of a taxicab driver (and former special forces major) named Korben Dallas (Willis) when a young woman (Jovovich) falls into his taxicab. Korben than has to gather four stones before a dark planet that represents pure evil reaches Earth."
