The Ultimate Fighter - 20 ª Season

For the first time in the history of the competition, The Ultimate Fighter will crown a champion. 16 of the most talented female fighters in the world arrive to the UFC training center to compete in a tournament to decide who will be the first first belt holder in the UFC's new 115 pound straw-weight division. Some are veterans of the women's fight organization Invicta, others chosen from an open tryout. Coaches Gilbert Melendez and current lightweight champion Anthony "Showtime" Pettis pick their squads, the women move into the house and begin training. Then, the teams face off in the first preliminary fight of the season, between Tecia Torres and Randa Markos.

Hard training by Team Melendez takes it's toll on the fighters while the women on Team Pettis are frustrated by their overbearing coaches. Then, second ranked undefeated Joanne Calderwood faces the number fifteen ranked Emily Kagan for a spot in the quarterfinals.

On the heels of Team Pettis' second win in a row, one of the fighters receives devastating news. After a silly game at the house turns raunchy, Heather Clark becomes an outcast on Team Melendez. Then in the third preliminary fight, #4 seed Jessica Penne of Team Pettis takes on #13 seed Lisa Ellis of Team Melendez, with a spot in the quarterfinals on the line.

After Team Melendez loses it's 3rd fight in a row tensions between Heather Clark and the rest of Team Melendez escalate. Urijah Faber takes over for Anthony Pettis for a few days as a special guest coach. Then, in the fourth fight of the tournament Team Pettis pits #1 ranked Carla Esparza against #16 ranked Angela Hill for a chance to advance to the quarter finals.

An injury forces one of the fighters out of the competition, and opens the door for another to get a second chance in the tournament. The Team Melendez fighters question the severity of Heather Clark's nagging knee injury. And the storied rivalry between #6 seed Felice Herrig of Team Pettis and #11 seed Clark finally comes to a head, as they face off in the fifth preliminary fight.
