The stakes are high as the first elimination round of the Summer Invitational approaches; members of Highlands Voices continue to disagree with some of Diana's choices; Stay Tuned lacks the confidence they need for their next performance.

Diana and the Highlands Voices prepare to do whatever it takes to come back from the previous week's loss; Deke and Stay Tuned plan a song that speaks to an iconic high school experience.

Deke tries a new tactic and decides to play it safe in the semi-finals; Diana hopes to take her group to the next level with some professional help.
