Stilled trapped in the time of the Three Musketeers, Rebecca is mistaken for Madame D'Urfe, an assassin hired to kill King Louis XIII. Jules and Phileas must persuade the Three Musketeers to reunite to rescue Rebecca, and save the King by defeating Richelieu. Of the Musketeers, Athos is dead and the other two are relucant, but are swayed to join. Porthos is a dead-ringer for Dumas in the 19th century. Adding further confusion, Richelieu is a twin for Fogg, Louis XIII for Jules, and D'Urfe for Rebecca. Apparently they have not just traveled in time, but into a parallel dimension of some sort. Rebecca plays along with the Cardinal, who is forced to kill the real Madame D'Urfe when she shows up so as to cover his tracks. Meanwhile, Passepartout works to discover the secret to the Phoenix to return all to their rightful place and time, aided by his own counterpart, a scientific genius. Rebecca fails to kill the King, and Richelieu hauls her away, then tries to have the King killed. Fogg, Jules, and the Musketeers break into the prison and a fight ensues. They rescue Louis, but Passepartout arrives, freezing time for everyone except his friends, who escape back to the 19th century. In the "present", they have the code. Fogg confronts the assassin Cavois, and they have a duel of "Russian Roulette" which Fogg wins.
