Lost and Found

While defeating Hawk Moth, Chat Noir gets thrown through a portal and is never seen again by the people of Paris. Mourning the loss of her partner, Ladybug disappears from the public eye and instead becomes Lady Noire in secret. She'd never leave Paris defenseless but she can't bear to be Ladybug without her partner.

Three years later, Lady Noire's life is suddenly turned upside down when she meets three strange boys, all who have powers without having a miraculous. After working together, they find out that the three boys somehow got teleported into an alternate universe.

How will Marinette be able to get 'the Big Three' as they're known, back to where they belong? And could it be too much of a stretch to believe their friend Adrien is the same one she lost that day three years ago?
