In an elaborate scheme, our heroic adventurers are lured to an ominous Scottish castle where the League of Darkness plans to brainwash Phileas Fogg into killing the Queen.

While there, Phileas is subjected to strange and secret treatments, and his friends can only watch while his personality appears to change in uncharacteristic and terrifying ways.

Their attempts at solving the mystery of Phileas's behavior lead to a momentous confrontation, with the League gaining the upper hand over them all. Rebecca, Passepartout, and Verne must escape from the clutches of the League and stop Fogg before he can carry out his deadly mission.

Will they be able to stop him or will the League finally win?
