On this episode they finished showing all of the contestant's performances and the teachers choose the TOP 9.
 
The top 9 got to form their new cells, and, after, the other trainees could choose whether to change their cells or remain as is and then all of the new cells were revealed and the voting started. 

The girls moved to the Planet Campus with each cell sharing a room and in the morning they had a mission in which they had to find the member's children photos and the winners got to decide the 2 cells they team up with on the first mission "Connect Mission". 

In the mission, 3 cells join to do one song together (as 9) and will compete with 3 other cells doing the same songs (8 songs in total). 

The teachers will choose the winner who will receive a benefit (they will receive double votes for a girl group song, three times for a boy group from the online votes) and will perform on M! Countdown. 

After the first mission, they will eliminate 16 cells (48 members), but the 48 eliminated girls will get a possibility to return with "Planet Pass" in which fans can vote for one girl in a cell.
