A young boy flies into a psychotic rage passing through customs, and Mithril flies into action. Is he some sort of brainwashed terrorist? Or is he something even more dangerous and sinister? Hidden away in Mithril's secret research facility, Captain Testarossa and Lieutenant Commander Kalinin attempt to find out. Has someone done experiments to fit the boy for the mysterious Lambda Driver? Suddenly, their research grinds to a halt when an armed group attacks and reduces the facility to a burnt-out shell. With Kalinin injured and missing in action, Captain Testarossa turns to the only person who can help her: Sergeant Sousuke Sagara. Little do they know that waiting in the shadows is their biggest enemy yet - and we're talking really, really big! The action and intrigue don't let up for a second in the third riveting volume of Full Metal Panic! All-new enemies, all-new mecha, and all your favourite heroes are all here in full force!
