What Is Can of Worms About?

The premise of Can of Worms in 360 words, with nothing given away. The full story follows below.

In a world where the extraordinary can erupt from a simple teenage impulse, a high‑school junior finds his ordinary life upended the moment he fires a desperate broadcast into the cosmos. The message, sent from a makes‑do satellite dish on a quiet suburban night, promises more than a fleeting glimpse of starlight; it opens a doorway for beings from far beyond Earth’s atmosphere to step into his world. The tone blends off‑beat humor with the restless energy of adolescence, setting a stage where teenage worries collide with intergalactic curiosity.

Mike Pillsbury is a lanky, introspective teen who’s never quite felt at home on the football field or in the expectations of his former‑star father. He spends his days wrestling with the feeling that he belongs among the stars rather than the bleachers, and his nights haunted by a vision that hints at something larger. Across the hallway, Katelyn Sandman dazzles as the popular girl who reaches out with a genuine invitation to help with school festivities, offering Mike a brief respite from his inner turbulence. Their budding connection hints at the possibility of grounding amidst the chaos that threatens to spill over their small town.

When the cosmos finally answers, the first visitor is an eccentric alien canine named Barnabus, who communicates through a quirky translating device and claims to represent a galaxy‑wide relief organization. He arrives with a bewildering entourage: a no‑nonsense alien lawyer demanding compensation for Earth’s “substandard living conditions,” and a laid‑back alien who offers to act as Mike’s interstellar representative. Their presence is both absurd and oddly sincere, infusing the story with a playful sci‑fi charm while underscoring the teenage protagonist’s struggle to make sense of a universe that suddenly feels far closer than ever.

The film balances earnest teenage coming‑of‑age moments with a light‑hearted, otherworldly spectacle. It teases the wonder of a stargate opening over a quiet suburb, the strain of parental expectations, and the thrill of unexpected companionship. Amidst the laughter and looming uncertainty, the story invites viewers to wonder what happens when a teen’s cry for connection echoes across the stars, and whether the answer will reshape his place on Earth—or beyond it.

Full plot

What Happens in Can of Worms?

The complete story of Can of Worms, from the first scene to the last, in 731 words (about 3 minutes). Spoilers throughout.

Spoilers ahead

Mike Pillsbury [Michael Shulman] is a teenage boy who believes that he is an alien and does not belong on Earth. He is injured during a football game and has a vision of an alien, which makes him question whether football is the right fit for him. His father, a former football star, urges him to persevere, adding pressure to conform to expectations even as Mike feels out of place.

Katelyn Sandman [Erika Christensen], a popular girl at school, reaches out to Mike for help decorating the upcoming Halloween dance. Their budding connection lightens Mike’s mood, but trouble arrives when his rival, Scott Schriebner [Marcus Turner], a football teammate and Katelyn’s friend, sabotages the dance’s light and music setup. The party falls into mayhem, and a frustrated Mike storms off, sending a desperate message into space via a satellite dish in hopes of being rescued. A bolt of lightning then destroys the dish, leaving his plea unanswered and isolating him further.

The next day, an alien dog named Barnabus [Malcolm McDowell] appears, speaking through a translating device. He reveals that, because of Mike, a stargate door has been opened. Barnabus explains that he represents a galactic disaster-relief organization and that he has arrived to take Mike off Earth. He warns that time is limited, as other aliens with ulterior motives are traveling through the stargate in search of Mike.

Mike’s reality becomes even stranger when The Bom [Bruce Lanoil], an alien lawyer, materializes with a blunt demand: sue Earth for millions of galactic credits for pain and suffering due to the planet’s alleged substandard living conditions. During a phone call with Katelyn, Mike finds himself distracted by The Bom’s odd eating habits, which convinces Katelyn that he’s not listening to her. The Bom leaves in a fury after Mike refuses to pursue a lawsuit. Nick [Adam Wylie], Mike’s friend, becomes convinced that his buddy is losing his grip on reality, especially as more alien visitors arrive.

Barnabus informs Mike that he opened a “can of worms” by sending his space message, signaling that Earth has progressed technologically and might lose its protection as a primitive planet. Despite the danger, Barnabus offers to take Mike somewhere far away to be alone, but first Mike tries to repair things with Katelyn. The Loafer Alien [Wally Wingert] interrupts this moment, proposing to act as Mike’s galactic representative and even suggesting a reality-TV future for his life as an immigrant. Mike declines the offer.

A flood of alien visitors arrives with offers for Mike, disorienting him further. Katelyn visits him and learns about the strange visitors, and Mike becomes determined to find a way off the planet. Just then, a Thoad — a dangerous alien known for capturing specimens — approaches, complicating matters. Nick’s younger brother Jay [Andrew Ducote] is suddenly pulled into the stargate and taken to the Thoad’s home planet, triggering Barnabus’s warning that the Thoad will keep abducting beings until he finds the perfect specimen.

To protect Mike, the children enlist Scott as bait to lure the Thoad through the stargate. Scott is initially skeptical, but the kids convince him that he’s the key they need. Barnabus and the others manage to slip through the stargate along with the three children, landing in a cave that houses the Thoad’s zoo of captured species from across the galaxy. Among the captives is an alien that resembles the ones Mike had imagined, hinting at a shared memory or knowledge he didn’t fully understand.

The Thoad, in his human guise, confronts Barnabus and the group. He shifts into his frog-like alien form but is briefly contained within a cage. Mike uses the Thoad’s key to release the imprisoned specimens, including Scott and Jay. Barnabus and the kids return to Earth, but the stargate remains open long enough for the Thoad to pursue them. Barnabus calls in intergalactic police to arrest the Thoad. As the police arrive just before the Thoad can drag Mike into the stargate, Barnabus emits a decisive bark that signals the moment of capture.

Back on Earth, during a football game, Barnabus informs Mike that the transmission he sent was deemed accidental and Earth regains its status as a protected planet. Though Barnabus offers to take Mike with him, Mike chooses to stay on Earth, saying farewell to his unusual but enduring friend and returning to the life and home he loves.
