In the first-season finale, the groups submit videos in hopes of securing the wild-card spot in the finals.

A music director is obstinate about keeping a set as is after a second-place finish, and he forces his team to practice making seductive facial expressions instead of singing and dancing.

A set change is made last minute, leading some singers to panic; a soloist has trouble memorizing the words to a song; a team president gets a bad case of stage fright.

A soloist struggles with a high note; a music director makes a song change late in the game; two singers begin to have doubts about the tattoos they got; a dating policy causes problems.

A music director makes a risky move; one group strain to create a captivating set; a team seek help with their choreography from a former member; a tough audience greet performers at a fund-raiser.

Illnesses and wardrobe issues plague one group; a new music director buckles as the pressure mounts; a burgeoning romance causes disharmony on a team; a soloist tries to overcome her stage fright.

A team is put in jeopardy by its soloist; campus rivals engage in a riff-off inspired by "Pitch Perfect"; a singer tries to heal the discord between his group and their opponents.
