Adapted from the fifth Alex Rider novel, season three sets the teenage spy on the tail of his greatest enemy: the elusive criminal network known as Scorpia. Under new leadership, the criminal cabal plan to extort the British Government using their catastrophic new super-weapon: ‘Invisible Sword.’ Free of The Department and aided by his closest friends, Tom and Kyra, Alex embarks on a personal mission to destroy Scorpia once and for all.
