 One year after the events in Jak 3, Jak and Daxter take up professional racing in a place called Kras City. Joined by their old friends, they are summoned by a woman named Rayne, who is...Krew s daughter? She apologizes to them for her father s actions, and proposes a toast in his memory. She takes out an odd-looking wine bottle, which she said that Krew instructed in his will that his closest associates must drink. After they all take a glass, Rayne brings out a hologram projector, which broadcasts his last message to Jak and company. Krew announces that the wine they drank is poisoned, follow by a maniacal laugh. The only way they can get the antidote is to win Kras City s big vehicle race, in his honor. And so, Jak and Daxter, Ashelin, Torn, Keira, and Sig are pitted against each other in combat racing for the ultimate prize: their life.
