In 2002, the NWA wrestling division gave birth to TNA (Total Nonstop Action) - an innovative form of wrestling that touted a breathtaking acrobatic style and unfolded in a decidedly unconventional hexagonal ring. Now, to celebrate four years of TNA action, a collection of brawlers including Jeff Jarrett, Sting, Christian Cage, The Truth, and Abyss all strap on their boots and prepare to do battle at the Slammiversary - an all-star wrestling event that doesn't pull punches and never slows until the last body has dropped.
