The shootout here involved a group of "lawmen," including Wyatt Earp and his brothers Morgan and Virgil along with Doc Hollliday, pitted against the Clanton and McLaury gangs.
Don't waste your money. Very difficult to hear & not very engaging. If you do buy a ticket do not go to top bleachers, the street noise is very loud & overbearing to actors who do not use microphones
Tensions between Wyatt Earp and the Cowboys explode in the famous Gunfight at the OK Corral. http://www.pbs.org/wgbh/americanexperience/features/timeline/wyatt/
