The Mogadorians have captured Six and Sam and brought them to Las Vegas, Nevada, as part of their mysterious master plan to get their revenge on the Garde.

Luckily for Six and Sam, they’ve yet to find a prison that can hold them. When they do manage to escape, and finally regain control of their Legacies, they will have to race against the clock to try to stop their old adversaries once and for all. And if they can’t succeed, they—and countless others—will suffer the consequences.
