Cowhairs want to drive farmers away from their lands. Luke takes matters into his own hands, and even Lotta's beauty and kindness can't hold him back. Signs suggest that there is also a third party in the background who benefits from the strife.

Lucky Luke becomes the Sheriff of Daisy Town and runs out all the criminals. Then the Dalton brothers arrive and try to get the Indians to break the peace treaty and attack the town.

By his dying father's last wish Joe is sent to the Wild West to become a real guy. The dreamy young man despises guns and fights likes poems and prefers bicycles to horses. Now his three teachers footpads all of them shall teach him otherwise. This doesn't work until Joe has to defend himself against gunman Morton who's jealous of Joe's love to rancher Ohlsen's beautiful daughter.
