EPISODE 4

When Marinette finds out that Adrien is about to spend a whole weekend in London with Kagami, she decides to write him a letter expressing how she feels before it is too late.

But a bedridden Master Fu entrusts her with a prescription and a letter for Marianne, an old friend to whom he could never confess his love.

Marinette gets confused and mixes the recipients up, accidentally giving her letter to Adrien to Marianne, who misinterprets its contents.

Hurt and heartbroken, Marianne gets akumatized by Hawk Moth. Now Backwarder and armed with a magic wand, she wants to make up for lost time by stealing it from others.

Will Ladybug and Cat Noir manage to stop her before it is too late?

And will Marinette be able to give the right letter to Adrien?
