Lance Sterling, a cocky secret agent of H.T.U.V. (Honor, Trust, Unity and Valor), is sent to recover an attack drone from Japanese arms dealer Katsu Kimura in
Japan. As soon as the buyer, cybernetically enhanced terrorist Killian, arrives, Lance breaks in against the orders of H.T.U.V. director Joy Jenkins, defeats Kimura and his gang, and manages to escape with the briefcase containing the drone. Lance returns to the H.T.U.V. headquarters to confront Walter Beckett, a socially inept
MIT graduate and outcast young scientist, for equipping nonlethal weapons into his suit. Walter tries to convince Sterling that there is a more peaceful way to save the world but Lance fires him before he can explain his latest invention: "biodynamic concealment". Lance discovers the briefcase to be empty and is confronted by Marcy Kappel, an
internal affairs agent, who reveals footage of Lance – actually Killian in a holographic disguise – leaving with the drone, labeling him as a traitor. Lance escapes the H.T.U.V. and decides to track down Walter to help him disappear. Meanwhile, Killian breaks into the H.T.U.V. covert weapons facility. While searching Walter's home for his invention, Lance ingests the concoction and transforms into a pigeon by undergoing "
chromothripsis". Before Walter and Lance can decide what to do next, Marcy and other H.T.U.V. agents chase the duo through the city, but the duo escape in Lance's spy car. The two track down Kimura at a resort in
Playa del Carmen, Mexico. There, they learn of Killian's whereabouts in
Venice, Italy before Marcy and the H.T.U.V. can capture them again. Arriving in Venice, Walter is confronted by the H.T.U.V., who are unaware of Lance's condition. Revealing that she knows about Wendy, Walter's mother who was a police officer who died on duty, Marcy tries to convince him to help turn Lance in, but Walter refuses. Suddenly, a drone distracts the H.T.U.V. and allows Walter and Lance to escape. The two discover the drone carrying the H.T.U.V. agent database, and Walter manages to retrieve it. However, Killian shows up, takes the database and prepares to kill Walter. With help from hundreds of pigeons in the surrounding area, they distract Killian and flee. Disguised as Lance once more, Killian escapes the H.T.U.V., shaking Marcy's suspicions of Lance upon her seeing him with a robot hand. Whilst underwater in a submarine, Walter reveals he planted a tracking device on Killian and locates him at the weapons facility. Walter manages to perfect the antidote and successfully turns Lance human again. Reaching Killian's hideout, Lance is concerned about Walter's safety and sends him away in the submarine. Once inside, Lance confronts Killian, but is knocked out and captured as Killian reveals he has mass-produced hundreds of drones to target everyone at the agency using the database as revenge for killing his crew in a past mission led by Lance. Noticing Walter returning in the submarine, Killian destroys it; unbeknownst to them, Walter survives with the help of one of his inventions, the inflatable hug. Once Walter frees Lance, the two escape and contact Marcy for support as the drones approach H.T.U.V. headquarters in
Washington D.C. Walter attempts to hack into Killian's bionic arm but when Killian realizes this, he tries to flee via air with a drone, but Walter catches up. Walter risks his life by trapping Killian in the inflatable hug and deactivates the villain's arm as Walter himself falls, but Lance, who has turned himself back into a pigeon, successfully flies for the first time and carries him to safety with help from other pigeons, while Killian is found and arrested. Despite saving the world, Lance – back in his human form – and Walter are fired for insubordination. However, they are quickly rehired by the H.T.U.V. as the agency could learn from Walter's more peaceful ways of handling villainy. ==Voice cast==
