Suburban Commando

Interstellar warrior Shep Ramsey is assigned to capture General Suitor, who has abducted planetary ruler President Hashina. He boards Suitor's flagship to confront the despot and rescue Hashina. The mission ends in disaster as Hashina is killed by Suitor, and the villain mutates into a berserk reptilian form.

Shep launches a desperate rescue attempt, but Hashina is killed by Suitor during the encounter. Suitor transforms into a monstrous reptilian creature, increasing the danger. Shep barely escapes by detonating parts of the flagship, destroying the ship as he escapes.

After the mission's failure, Shep's superior orders a vacation, but his frustration leads to an accident. He smashes his control systems and crash-lands on Earth, forcing him to stay until repairs can be completed. He experiences a jarring culture shock, making the adjustment a struggle.

On Earth, Shep struggles with local customs and his temper, which creates friction with the people he meets. He encounters a mime artist, whose presence underscores his awkward attempts to help others. The encounters set the tone for his awkward adaptation to terrestrial life.

Charlie Wilcox, a timid architect, rents out his hobby shed as a vacation cabin and ends up hosting Shep. The unlikely lodger unsettles Charlie and attracts the attention of Beltz's company. Shep's presence and gear begin to reveal themselves.

Charlie grows suspicious and starts spying on his mysterious guest. He discovers Shep's advanced equipment and realizes the power sources are traceable. This discovery sets up pursuit by Suitor's men.

Suitor's men mobilize and dispatch two intergalactic bounty hunters, Knuckles and Hutch, to track Shep. They close in as Shep and Charlie scramble to patch the ship and stay ahead. The threat intensifies as they draw nearer.

The ship needs rare crystals to repair, with samples hidden in Beltz's office. Charlie helps Shep infiltrate Beltz's facility during a company party to obtain them. They defeat the pursuing bounty hunters and return home to repair the ship.

Suitor returns to Earth and takes Charlie's family hostage, coercing Charlie into guiding him to Shep. The hostage situation raises the stakes for both men as they confront the threat together. Shep steels himself for a dangerous showdown.

To protect Charlie's family, Shep uses a lose-to-win tactic, setting his ship to self-destruct and surrendering to Suitor in exchange for the hostages' release. He endures torture from Suitor before planning to kill him, testing the warrior's resolve. Charlie's actions soon pivot the balance.

Charlie returns to help Shep and wounds Suitor, who then mutates into his monstrous form. Shep stuns the monster with improvised electrical wires, allowing them to escape as the ship explodes. Suitor is destroyed, ending the threat for good.

Shep escapes Earth aboard the bounty hunters' ship and takes Beltz's secretary Margie with him for a quiet family life. The pair depart into space, seeking a peaceful future away from intergalactic conflict.

Back on Earth, Charlie returns to Beltz's office the next morning and confronts him, quitting his thankless job in front of witnesses. The experience leaves him more confident and ready to stand up for himself. The act marks a personal transformation sparked by Shep's presence.

Charlie solves his final problem by using one of Shep's weapons to destroy a set of malfunctioning traffic lights that never change at the right time. His bold move earns cheers from motorists and signals his growth as a new kind of hero. The closing moment hints at a hopeful future for both Charlie and Shep.
