Plot

In New York City 1880, the Dalton brothers (Joe, Jack, William and Averell) escape from a court trial regarding the Daltons' bank salesman cousin disgracing their name and plunder several banks across New York, while Lucky Luke hunts for them. Upon placing their loot of stolen cash in an empty wagon at Central Park, New York, which was in construction at the moment, and attempting to blend in with the crowd in order to avoid detection from the police, Averell unwittingly blows their cover in front of the police, resulting in a wild police chase across New York.
