Arriving at the town of Fort Smith with a prisoner, Lucky Luke is surprised to find a place in turmoil and a thoroughly annoyed sheriff. Belle Starr, a rich ranch owner, keeps posting bail for every bandit arrested in town, with the complicity of a corrupt judge, before recruiting them in her own gang and carrying out various attacks and robberies. Unfortunately, she is also such a pillar of the community that no one believes she could possibly be guilty...

When oil suddenly gushes from the ground in Whitney, it makes prospectors very happy, but not the inhabitants, for a pestilential smell soon covers the small town. Abandoning her home, Whitney's elder Miss Bluemarket moves to Smithville with her three pets - three adult buffaloes. Her search for a new home makes her easy prey for unscrupulous estate agents, and soon she finds herself owning a property whose mere name has the locals shaking in their boots: the Bates ranch...

In a fort on the Frontier, the 7th Cavalry keeps a vigilant watch over the Wild West. It is a time of peace with the local Natives, and all is well, thanks - at least in the colonel's mind - to the regiment's lucky mascot. But when that dog mysteriously vanishes and bad luck begins to plague the unit, it becomes necessary to find a replacement. The colonel picks Rin Tin Can for the job... and then the real trouble begins!

After a fellow inmate, having received a blow to the head, forgets his own name and is freed as a brand new man, the Daltons start pretending to be amnesiac in order to escape the prison. So as to test their supposed amnesia - and hopefully allow them to retrieve their memories should it be real - they are put in familiar situations: bank hold-ups, train robberies - under Lucky Luke's supervision, of course.

Luke gets to help set-up the legendary Pony Express! In 1860, getting from Missouri to California on the West Coast took a long, long time - not to mention a certain degree of courage. Annoyed at the delay in communication, the federal government offers a grant to whoever can solve the problem and set-up a fast, reliable mail system linking East and West. In response, entrepreneur W.H. Russell founds the Pony Express company: fearless men riding day and night, changing horses at way stations. But not everyone likes that idea...The 46th adventure of Lucky Luke, and the Old West at its funniest!

In 1874, President Grant authorises the construction of a bridge over the Mississippi. Until then, passage between St. Louis and East St. Louis was only possible on ferries. But the ferry company is owned by two brothers who have been getting rich by forcing passengers to wait in the hotels and restaurants they own on both sides of the river. The two crooks are doing everything in their power to prevent the bridge from being built - until Lucky Luke arrives, of course...

Horace Greeley is heading west with his printing press and his rock-solid belief in the power of the press, printing issues of his DailyStar as he goes. But his insistence on publishing the truth isn't making him universally loved. When Lucky Luke meets the quirky journalist, he agrees to help him settle in Dead End Gulch-and protect him against those who would rather not see their dirty deeds in print.

Sensational news in the United States: the great actress Sarah Bernhardt is coming from France for a grand tour across the continent. The world of show business is in effervescence but some, such as the League of Virtue, are opposed to the tragedian's coming, because of her sulphurous reputation. President Rutherford B. Hayes, a theatre-lover, asks Lucky Luke to look after the lady, ambassador of French culture and charm...

Everyone's heard of the Gunfight at O.K. Corral: the most famous shootout of the Old West, between the Earp brothers and Doc Holliday on the side of law and order, and the Clanton brothers and their gang. A legend told many times in books and films, in sometimes contradictory versions... Fortunately, here is the definitive version at last, restoring the unvarnished truth of what is another triumph of... Lucky Luke!
