The book ends with Billy, Emmett and Sally heading off to San Francisco, while Duchess drowns trying to save his money from flying away (rather than floating back to safety). Ultimately, Billy is able to guess the safe combination, and Emmett puts Duchess (who can't swim) in a leaky boat on the lake with his share of the money. Woolly kills himself (which Emmett thinks was his plan all along since he was unhappy and misunderstood by his family), and Emmett and Duchess have a confrontation that turns violent.

When they finally all reach Woolly's grandfather's lakeside house (where the safe with the money is), it turns out Woolly doesn't even know the combination to the safe. Meanwhile, Duchess is also trying to settle some debts against along the way, and he attacks their former warden and other people. They are aided by Sally, a family friend, and Ulysses, a black man they meet on the train. When Emmett declines, Duchess "borrows" Emmett's car, forcing Emmet and Billy to stowaway on a train to New York to find Duchess and Woolly and reclaim it. However, two guys (Duchess and Woolly) have snuck out from juvie and have followed Emmett home, hoping to convince him to help with a caper in New York to take back Woolly's $150K trust fund (which Woolly has been deemed "unfit" to access).

Billy hopes to find their mother (who left them 8 years ago) there.

The two-paragraph version: Emmett (18) has just gotten out of juvie and is now planning to drive down the Lincoln Highway to move to San Francisco with his younger brother Billy (8).
