FOR Y'UR HEIGHT ONLY

The diminutive Agent 00, the number 1 agent from the Secret Agency, is provided with a number of new hi-tech gadgets from his boss, and then sent to stop the mysterious warlord Mr. Giant, who has just kidnapped Dr. Kohler, a foreign scientist visiting Manila to offer his latest invention, the N-Bomb, to the government. Mr. Giant intends to use the lethal weapon to take over the world, but Agent 00 is ready to stop him.

He can count on the help of Irma, a fellow agent who has infiltrated Mr. Giant's criminal organization, working for the drug traffickers that are headed by a gangster named Cobra. This leads to many battles between Agent 00 and the villain's henchmen. Once Irma's cover is blown, she is taken prisoner as a bait and sent to Mr. Kaiser, Mr. Giant's second-in-command, who keeps her in his lair. In order to find Kaiser, Agent 00 enlists the help of other Bond girl types, such as night club enthusiast Anna and criminal reporter Marilyn, romancing his way to their allegiance. After flushing out and killing criminal bosses of increasing importance, and all of their henchmen, Agent 00 reaches Kaiser, but by then Irma has been shipped to Hidden Island, Mr. Giant's super-secret lair.

After finding the secret location of the island, Agent 00 uses a prototype size-compatible jet pack to get there, and calls for reinforcements. He confronts and kills Mr. Giant himself (who is revealed to be a dwarf himself, although taller than Agent 00), then along with the squad of agents from the Secret Agency, Agent 00 and Irma clean the island of all remaining henchmen. However, right after a freed Dr. Kohler has finally reached safety, Irma is shot and killed. In the final scene, Agent 00 is seen paying respect on her tomb.

Agent 00 defeats Mr. Giant and his organization, rescues Dr. Kohler, but Irma is killed and Agent 00 mourns her at her tomb.

The film wraps up its wild espionage plot with Agent 00 successfully thwarting a catastrophic threat, rescuing the scientist, and eliminating the villain. However, the loss of Irma adds an unexpectedly somber note, underscoring that even parody adventures come with real stakes. The closing scene highlights Agent 00’s resilience and capacity for genuine emotion, giving the film a bittersweet coda amid its comedic chaos.
