The only time ALIBI gets stage fright is when they see a ghost!

The girls of the hit K-pop group ALIBI think theyve found the perfect place to rehearse for their next big tour performance: an ancient Greek amphitheater by the sea. But their dream space turns into a nightmare when eerie music fills the air and the ghost of a famous composer appears without warning. Now a cursed symphony, a troubled spirit, and a terrifying demon threaten not just their tour, but the safety of the whole village.

Armed with their new demon-detecting gadgets and their combined wits, the girls must follow the clues, uncover the lies, and unravel the mystery before a powerful demon steals the stage for good.
