In 1880 a group of strangers board a stagecoach. The stagecoach is heading eastward from Tonto, Arizona to Lordsburg, New Mexico. Among these strangers is Doc Boone an alcoholic doctor, Dallas a prostitute, Mrs. Mallory a pregnant lady and Samuel Peacock a whiskey salesman. Marshal Curly Wilcox tells the stagecoach driver, Buck that his regular ride along guard went hunting for Ringo Kid. Wilcox decides to ride in place of the regular guard when Buck informs him the Plummer brother's are in Lordsburg.
The Plummer brothers killed Ringo's father and brother and Ringo has sworn to get revenge. Prior to the stagecoaches departure the group is informed by Lt. Blanchard that Geronimo and the Apaches are on a warpath. Lt. Blanchard tells the group he and his men will escort them to Dry Fork. However from there onward they will have no military protection. Moments before departure the coach is hailed down and two more passengers board Hatfield a southerner and Henry Gatewood a banker.
Along the way they come across Ringo Kid, stranded because his horse had left him. Curly takes Ringo into custody. The group reaches Dry Fork and is hesitant to proceed onward over lunch the group votes to continue to Apache Wells.

Moments before Hatfield tries to pull the trigger he is fatally shot. Soon after that the U.S cavalry arrives and rescues the group. Later that day the group arrives in Lordsburg, Gatewood is arrested for embezzling $50,000 while Ringo goes to find the Plummer brothers and kills all three of them. Ringo then returns expecting to be returned to jail. However Curly lets Dallas and Ringo escape.

The story line in Stagecoach is very linear. Events happen in such a way that you would expect them too. Each event or section of the story happens in result of what happened prior.
