Underground 2 takes place in Bayview after the events of Need for Speed: Underground. The prologue begins with the player driving in a Nissan Skyline GT-R. He then receives a race challenge from a rather ominous personality who offers him a spot on his crew, but "won't take 'no' for an answer." The player races off - despite Samantha's warnings-- to find the guy only to be ambushed by a mysterious driver in an SUV Hummer H2 that totals his Skyline. The driver makes a call confirming the accident, and the flashback fades out..
Fast forward to the present day, where we see the player arriving in Bayview via airplane, with a note from Samantha referring him to her friend Rachel, who will set the player up there. He also has the keys to Rachel's Nissan 350Z, which is waiting for him outside the airport. The player then has the option to complete a few races in the car before inevitably returning it to the car lot, where Rachel will allow him to choose his first vehicle. This one is free, as it was paid for by the player's insurance from his totaled Skyline.
It is then that the player embarks on a quest to become the top racer in Bayview and eventually take down the man who sabotaged his ride in the flashback, who turns out to be Caleb. After winning many races, the player runs into Caleb's street racing gang, the Street Reapers.The gang has the same vinyl, paint, and rim set. The player challenges them to a series of URL races and eventually gets Caleb's second in command, Nikki, to go to your side. Rachel tells the player that Caleb has been manipulating the sponsorship deals throughout Bayview towards him. After the player beats the Street Reapers, an infuriated Caleb challenges the player to one final race in his custom Pontiac GTO. The reward for beating the game is all cars and parts. If you beat the game 100% you get Caleb's car.
