Lucky Luke - Volume 36 - The Daltons Redeem Themselves

When a senator comes up with a probation program to redeem criminals in the
USA, the Supreme Court offers him a chance to prove the feasibility of his
idea... by trying it out on the worst Old West villains ever: the Daltons. As
usual, it’s up to Lucky Luke to keep an eye on the terrible four during their
month-long trial period. If they can refrain from any crime during that time,
they will be set free as good citizens...
