The film begins with an intense scene set in a dense forest where a secret U.S Agent is navigating with a map and a glass of water in his hand. Suddenly, he is shot, igniting suspicions of an inside job within the government. Without this agent, the crucial package they aim to secure becomes unattainable, as he was the only one they fully trusted with the assignment. The captain, realizing the urgency of the situation, mentions that there is one other individual who might assist them, although he admits that this person is not favored due to his reckless nature.

The narrative then shifts to a bustling market scene where the man in question, Nick Pirandello, is busy working at a fish stall. During his covert operations, he spots a rival agent and promptly pursues him, eventually trapping him inside a truck. The rival agent, attempting to charm Pirandello into releasing him, ultimately falls for Pirandello’s clever ruse where he feigns having swallowed a poison pill. Under pressure, the agent reveals that the map they are seeking is located in room 505 at the Highway Hotel. Pirandello, still playing the role, leaves the agent begging for the antidote, only to retort that he never actually took the pill, knocking him out cold instead.

Meanwhile, the tension escalates as Pirandello searches for the map within the hotel located inside an alarm clock, just as a group of KGB agents armed with shotguns position themselves outside. With adrenaline pumping, Pirandello creatively fashions a makeshift rope with shoelaces, allowing him to escape through a fire escape and into another hotel room. A comedic twist occurs when a KGB agent breaks down the door, only to find Pirandello under the covers with another woman. Without hesitation, he turns and shoots the KGB agent, narrowly evading capture.

After delivering the map to his captain named Cunard, Pirandello finds the plan thwarted by the captain’s assistant who betrays them by tossing the map out the window. It is snatched up by rival agents who are now onto their game. Cunard briefs Pirandello about their new strategy: find a look-alike for the fallen agent to impersonate him during a critical exchange. The look-alike, Bob Wilson, is portrayed in a comedic light, as he nearly collides with a milk truck while driving.

Upon arriving home, Wilson is confronted by a chaotic household where his children have been picked on at school. Determined to retrieve his son’s stolen bike from a gang of troublemakers, he finds his attempts thwarted when the gang members overpower him, leading to an embarrassing defeat that sends him home dejected. However, a twist of fate introduces him to the world of espionage when Pirandello confronts him in the garage asking for help. An absurd exchange unfolds as Wilson unsuccessfully attempts to fend off Pirandello with a rake, only to find himself caught in a whirlwind of chaos, intrigue, and unexpected camaraderie.

As the plot thickens, Pirandello reveals the gravity of their situation, insisting that they must be in Washington, D.C. by 8:00 AM on Monday. Wilson, however, remains reluctant, preoccupied with his everyday life and responsibilities. Pirandello, determined and inventive, constructs weaponry out of makeshift materials while they narrowly escape multiple attempts on their lives by rival agents. Their precarious journey is underscored by moments of dark humor, absurdity, and the stark realization that things are escalating beyond their control.

The pair travels through various states, encountering eccentric characters and outrageous scenarios, including an encounter with a humorous milkman which leads to a revelation about Wilson’s homelife. In the midst of thrilling chases and comic sketches, it becomes evident that Wilson is slowly being drawn into the espionage world, gaining confidence and surprising skills along the way.

Eventually, they find themselves in a showdown with KGB agents, where Wilson unexpectedly proves himself to be a bit more capable than anyone anticipated. Amid the chaos, he learns about an extraterrestrial mission involving a crucial package that holds the key to Earth’s survival. As both characters navigate treacherous waters filled with double-crosses, mistaken identities, and their respective personal crises, they discover the strength of teamwork and friendship in the face of danger.

The climax unfolds in a dramatic confrontation which results in revelations that shake Wilson’s understanding of right and wrong. A heartwarming resolution brings him back home, only to find his domestic life is quite different, leading to humorous ramifications with his family. He confronts the milkman in a final showdown, asserting his newfound confidence and perspective on life. With Wilson’s journey from an everyman to an unexpected hero, the film wraps up on a high note, reinforcing themes of perseverance, trust, and the hilarity that often accompanies the absurd challenges of life.
