Siblings Mimi and Luke unwittingly resurrect an ancient alien overlord who was entombed on Earth millions of years ago after a failed attempt to destroy the universe. They nickname the evil creature Psycho Goreman (or PG for short) and use the magical amulet they discovered to force him to obey their childish whims. It isn’t long before PG’s reappearance draws the attention of intergalactic friends and foes from across the cosmos and a rogues’ gallery of alien combatants converges in small-town suburbia to battle for the fate of the galaxy.
SPOILERS AHEAD
PG: Psycho Goreman Plot Summary
After an intense match of their homemade game “Crazy Ball”, siblings Mimi (Nita-Josee Hanna) and Luke (Owen Myre) discover a strange, glowing gem in a hole that Luke has been forced to dig by the domineering Mimi for losing. That night, an alien monster emerges from the hole. The monster enters an old shoe factory and brutally kills a group of thieves hiding out there. The next day, Mimi and Luke follow a trail to the shoe factory discovering the monster. The monster identifies himself as “Arch-Duke of Nightmares”, a deadly alien warrior imprisoned on earth after attempting to destroy the galaxy in a rampage. He prepares to kill the children only to discover Mimi is in possession of the gem which allows whoever wielding it to command him. Excited at this opportunity, Mimi dubs the alien “Psycho Goreman” or “PG” (Matthew Ninaber and Steven Vlahos) for short and quickly gets to work commanding PG around despite Luke’s concerns. Meanwhile, a group of aliens called the “Planetary Alliance” discover PG has escaped the imprisonment they cast him in. They send Pandora (Kristen MacCulloch), a noble warrior and member of PG’s mortal enemies “The Templars” to stop PG. Pandora assumes the appearance of a human woman and travels to Earth.
Mimi and Luke introduce their friend Alastair to PG. PG tells the children how he was a slave to the Templars on his home planet Gigax until he discovered the gem which bonded with him, giving him endless strength and power. He assembled an army called “The Paladins of Obsidian” and overthrew the Templars. Filled with bloodlust, PG vowed to destroy the galaxy until the Templars and Planetary Alliance worked together to steal the gem and banish PG. When the children leave, PG uses a TV to broadcast a call for help to the Paladins of Obsidian. Alastair comes to Mimi and Luke’s house for dinner. Mimi, who has a crush on Alastair, is annoyed when she is abandoned by the boys so they can play video games. Mimi summons PG to the house and asks him to make Alastair an affectionate playmate. PG proceeds to mutate Alastair into a giant brain creature. Mimi and Luke’s parents Susan (Alexis Hancey) and Greg (Adam Brooks) see PG and Mimi introduces him to them, showing how she can control him. Mimi forces PG to accompany the family on activities and become a reluctant friend to the family.
PG communicates to Luke privately through a nightmare demanding that he steal the gem off Mimi and returns it to him, promising to spare Luke in his rampage if he does so. Luke refuses, clearly scared of Mimi. One day while out with PG and the mutated Alastair playing Crazy Ball, the kids are approached by two officers who attack PG. PG mutates one of the officers into a deformed “Bio-cop” while the other officer escapes. While walking in the woods, Mimi jokingly commands PG to kill Luke, upsetting him. Pandora arrives at the police station and interrogates the officer that escaped PG for information. In the woods, the Paladins of Obsidian arrive in front of the group. Believing he will be rescued, PG orders them to kill Mimi and Luke only for the Paladins to reveal they like life without PG and worked with the Templars to overthrow PG. PG tries to attack them but Mimi stops him as punishment for commanding the Paladins to kill them. Mimi forces PG to apologize and when he does, allows him to fight back. PG kills the Paladins but is injured in the attack.
Susan and Greg have another argument over Greg’s laziness. PG comes to Greg in a vision demanding he collects him and the children from the woods. Greg does so and they drive back to the house where Pandora is waiting with Susan. Susan suggests they hand over PG to Pandora with Luke rebelling against Mimi and siding with Susan and Pandora. Greg sides with Mimi and drives away with PG, hiding in the shoe factory. Pandora reveals her true form before transforming Susan into an armored warrior to help take down PG. At the shoe factory, PG states the gem is the only way to heal him which Mimi agrees to give to him if he spares her and her family but Mimi discovers she has lost it. Pandora, Susan, and Luke arrive at the shoe factory with Luke being revealed to have stolen the gem. Mimi and Luke fight over the gem while Susan and Greg battle over their marriage. Luke convinces Mimi that the power of the gem and PG have corrupted her.
PG challenges Pandora to a fight according to Templar’s code, meaning that Mimi is allowed to select the battle. She chooses Crazy Ball. Mimi’s team wins but Pandora moves in to attack Mimi and PG. Susan uses her powers to save Mimi but is quickly reverted back to human form by an enraged Pandora. Luke and Mimi reconcile, singing a song with Greg and handing the gem to PG. PG retrieves his power and devours Pandora. PG returns the gem to Mimi, stating that after witnessing the family’s affection for each other, he is now powered by love and he will use that love to destroy the galaxy but promises to spare the family. The family bids farewell to PG and watches as he begins to destroy their town.
The Ending
Meanwhile, Alastair continues to live as a giant brain mutant while the Planetary Alliance debates killing themselves before PG can reach them.
