The Nationals are back on - but which team is going? A-Troupe or B-Troupe?

Talented and hungry dancers show up for the Challenge, which could shake The Next Step.

Auditions continue, and a new A-troupe will be formed.

Richelle and Shad hold auditions to find a soloist to be the lead in Step Inside.

Kenzie goes through her first challenge as Dance Captain of A-Troupe, and Kingston has trouble picking a duet partner.

Lily struggles to focus on dance while avoiding more pressing issues. Ozzy tries to find Richelle the perfect venue for Step Inside.

Jude, Ethan, and Ebby compete to become the Nationals soloist and Ozzy and Heath's investigation has devastating results.

Amy hopes to fail her prestigious audition and Piper wonders if that’s really a good idea. Meanwhile, Richelle and Shad try to convince Nick to invest in Step Inside.

Shad surprises Richelle and they share a beautiful moment. Heath vows to mend Ozzy and Kingston’s relationship, but his efforts morph into an eventful search for the mole.

When the mole’s identity is revealed, Richelle and the Step Inside cast must start from scratch the day before their big performance!

It’s showtime! With an online audience waiting, plus a few surprise visitors, the pressure is on… but Richelle discovers she may be about to lose everything she’s worked for.

Intermission is over! Piper and Amy bet on themselves in an attempt to impress Drew before Richelle and TNS dance what might be their final number as a team.
