For the first time ever sixteen undefeated fighters from around the world, eight lightweights and eight featherweights, come to Las Vegas to compete on The Ultimate Fighter. The competition begins with coaches Daniel Cormier, the current UFC light heavyweight champion, and Stipe Miocic, the current UFC heavyweight champion, putting the fighters through drills to evaluate their skills. Then after UFC President Dana White arrives and greets the fighters, the coaches pick their teams and choose the first preliminary matchup. After the fighters move into The Ultimate Fighter house, training begins with both teams holding their first practices. The tension continues to build as the teams prep their fighters for the first preliminary matchup of the season.

With the tournament now officially underway, Stipe Miocic and his coaching staff decide it's time to get the pranks started. Before practice, they redecorate Team Cormier's locker room by adding some questionable pictures to the walls. Stipe then turns his attention to his first featherweight fighter, who is extremely confident that his well-rounded game will be too much for his opponent to handle. As the blue team arrives for their practice session, they are surprised to find their defaced locker room. Cormier is amused and immediately retaliates in shocking fashion. During practice, a fighter loses his calm and proceeds to question Cormier's instructions. The two hash things out in front of their team. Back at the house, the fighters get to know each other and one of the featherweights opens up about his life.
