The famous warrior and scoundrel Harry Flashman has a new hobby. This time he falls under the powerful charm of international adventurer Lola Montes, playful as a kitten and dangerous as a ball of barbed wire. In parallel with this event, the careless ladies' man manages to make himself a serious enemy in the person of the young German aristocrat Otto von Bismarck, whose iron fist is already beginning to threaten a royal Europe that feels too at ease. Flashman has no idea what a dangerous joke Mother Nature played on him (not without the participation of his honorable parents, of course). The mission in Germany promises to be unforgettable.
