Invisible Agent

In Griffin's Manhattan print shop, four armed foreign agents confront him and reveal his true identity. They demand the invisibility formula and threaten his fingers if he refuses. Griffin manages to escape with the formula and vanish into the night.

Griffin reluctantly agrees to share information with U.S. officials, but only under a strict limitation: the serum can be used on him alone. He begins a wary cooperation as America enters World War II. The arrangement marks his first formal linkage to Allied authorities.

On the way to a secret mission behind German lines, Griffin injects himself with the invisibility serum. The effect takes hold mid-flight, leaving him disappearing before the eyes of pursuing troops. The mission hinges on this dramatic new advantage.

Griffin descends behind enemy lines and lands, shedding his clothes as part of the awkward reveal of his altered state. The German troops are shocked and confused by his sudden disappearance and later reappearance. The operation begins with his stealth and deception intact.

Griffin evades pursuit and seeks out Arnold Schmidt, a coffin-maker who becomes crucial to his mission. Schmidt explains the next steps and helps steer Griffin toward obtaining the spy list. The unlikely ally provides a human connection in a tangled web of espionage.

Maria Sorenson tries to coax information from Karl Heiser during a private dinner, with Griffin serving as a discreet witness. The exchange devolves into suspicion, and Sorenson is placed under house arrest. The dinner scene exposes fragile loyalties among the Axis agents and their allies.

Griffin tests the limits of invisibility by playing tricks during the private dinner, then reveals himself through a robe and facial cream. Sorenson responds with attraction and begins to reconsider her loyalties. Their uneasy alliance deepens into something more personal.

Stauffer returns from the U.S. and unsettles existing loyalties, while Heiser is arrested. Griffin walks into a trap but nonetheless manages to seize the agents' list and starts a fire to cover his escape. The theft destabilizes the Axis network and escalates the chase.

Griffin delivers the captured list to Schmidt for transmission to England, hoping to cripple Axis espionage on U.S. soil. Schmidt accelerates the transfer, but the pressure from intelligence rivals remains high. The list becomes the focal point for both sides' pursuit.

Griffin infiltrates a German prison to pull information about a planned attack on New York City from Heiser. In exchange, Heiser helps ensure Griffin's escape from imminent execution. The mission tightens the clock on both sides.

Ikito's men capture Griffin and Sorenson at the German Embassy amid the escalating chaos. Heiser works behind the scenes to move the plan forward, but time is running out. The trio escapes with a bomber and tears toward England as Axis defenses close in.

England's air defenses shoot down the escort as Griffin and Sorenson parachute to safety in England. In a hospital, Griffin reveals that he is visible again, despite the facial cream, and Sorenson admits she has been an Allied double-agent all along. The two share a kiss as she embraces the challenge of discovering how he regained his visibility.
