The Princess and the Singer (S02E14)

While exploring the quaint European nation of Morvania, Kimber encounters Princess Adriana, a teenage royal who bears an uncanny resemblance to her. When Adriana escapes her confines, her ambitious cousin Lexa sends her goons to find and return her to the palace. During a chance meeting, Lexa's henchmen mistake Kimber for Adriana and kidnap her, locking her away in a tower. Realizing the real Adriana is with the Holograms, Lexa enlists the Misfits to set a trap at the Holograms' hotel, intending to blow up the stage and eliminate Adriana. However, the Misfits crash the event just in time to thwart the explosion. The Holograms then manage to rescue Kimber, leading to Lexa's arrest for her schemes, while Adriana finally ascends to the throne as queen.
