Super spy Lance Sterling is the top agent at his organization, renowned for his smooth charm and impressive combat skills. After a critical mission to recover an attack drone from the villainous Japanese arms dealer Katsu Kimura, Lance finds himself framed for stealing the very weapon he retrieved. With the agency now on his tail and his reputation at stake, he seeks help from an unlikely quarter: Walter Beckett, a young, socially awkward tech genius who works in the gadgets lab. Walter has always been an advocate for non-lethal weaponry, believing in using science for peace rather than violence, which puts him at odds with the agency’s traditional approach.

As Lance turns to Walter for assistance to clear his name, he accidentally ingests one of Walter's experimental inventions, leading to an unforeseen transformation that puts his career as a spy in jeopardy. This sudden change forces Lance to adapt to a whole new set of challenges while trying to stay under the radar from his own agency. Meanwhile, he and Walter must learn to work together despite their polar opposite personalities and views on espionage. With time running out and Lance’s enemies closing in, they embark on a high-octane mission to thwart the sale of the stolen weapon and prevent a global catastrophe.
