The begrudging Giusi Malvado and his spy, the abject Nino, discover that Alex is none other than Princess Alexandra of Kieland. Set on revenge against the Musketeers of Orleandia, the evil pair abduct her under the very noses of Bastien and his Musketeers, who are too busy to save the Tsar of Kasak and his daughter from a disastrous battle to notice the plot against one of their own. Bastien soon realises that Malvado's evil plan is to ransom Alex to the powerful Crowsnest who will surely use her to get King Charles II to abdicate and surrender Kieland to the Republican army once and for all. Torn between, friendship, love and loyalty to his King, Bastien is desperate to get to Kieland to save his best friend. But how much are the Musketeers willing to sacrifice to rescue one of their own?
