Lucky Luke must get Billy the Kid to New Mexico so he can be tried and put in jail. They both set out on the road, Lucky Luke assisted by Rin Tin Can. But Bert Malloy has promised the Kid he would set him free…
Kid Luck, still travelling with Old Timer, arrives in Mushroom City.
After months in the wild, they’re both glad to find a place where
they can have some fun! While the old gold miner has every intention
to enjoy himself, though, he immediately sends Luke … straight to
school! A horrible sentence for the young cowboy-in-the-making, who
is about to meet a quartet of already nasty little brats, and a
pistolero with somewhat … flexible morals!
