The Easter holidays are coming up and Max can't wait to go back to the farm to see Ben, Eleanor, Francis and Linden and escape a life she is convinced is more cursed than anyone she knows. She is even more excited to receive an invitation to attend a meeting at Spyforce HQ in London and Max and Linden board one of Spyforce's invisible super fast jets to make the trip. On reaching Spyforce headquarters they meet an extremely interesting collection of characters. But nothing shocks Max and Linden more than finding out that Alex Crane is real! Mr Blue is once again up to no good. Spyforce have come across information that Blue has invented a concoction, that when eaten, controls minds. Max and Linden, along with Ella and Alex and the team at Spyforce, must once again foil the evil work of Mr Blue before he creates an army of kids under his control.
