A musical episode. Adrien, upset because he's spending his first Christmas without his mother since she passed, and believing his father doesn't want to spend time with him, turns into Cat Noir and roams Paris. His father discovers he's missing from his room and becomes worried. When Marinette learns of this, she turns into Ladybug and sets out to find Adrien. She discovers him with a Santa Clause, whom she mistakenly takes for being akumatized and she attacks him, which in turn upsets him and incidentally causes him to fall victim to Hawk Moth, becoming Santa Claws.
