SEQUEL TO BLIND. Adrien and Marinette are living their double-lives together without the rule of keeping their identities secret for each other. But their relationship gets tested as Hawk Moth lures in the shadows with a new villain. Only this time the past is a worse enemy, as Cat Noir has to protect his partner and make sure she doesn't get the same fate as his beloved mother.

After defeating an akuma with chemistry powers, Marinette accidentally got herself blind and gets really scared of how she'll handle her double-life. Even if her miraculous gives her a little vision, she still can't handle her life as Marinette, especially now when Cat Noir visits her every evening. But when she's blind she sees him differently. And her heart almost forgets Adrien.
