The main event was a best two-out-of-three falls Lucha de Apuestas, or bet match where both Rey Escorpión and Último Guerrero "bet" their hair on the outcome of the match and the loser was forced to have all his hair shaved off afterwards as per Lucha Libre traditions. The show also hosted two first-round matches of CMLL's 2015 En Busca de un Ídolo ("In Search of an Idol") tournament where Esfinge wrestled Canelo Casas and Delta was supposed to face Blue Panther Jr., but wrestled Hechicero instead. The show contained four additional matches. Although it was not announced ahead of time, the first six matches of the show were broadcast live on the Terra Networks' home page for free.
