The Gate II: Trespassers (also known as Gate II: Return to the Nightmare) is a 1990 horror film and a sequel to the 1987 film The Gate. It was directed by Tibor Takács and was a co-production between the United States and Canada. Louis Tripp reprises his role as Terrence "Terry" Chandler, a teenager who opens a gate to Hell.
It has been five years since Terry (now known as Terrence) and his friend, Glen, accidentally opened up the Gate in Glen's back yard, releasing demonic forces that the two of them had to banish. Glen and his family have moved away, and Terrence's broken family has grown worse. Still grieving over his mother's death, and with his dad wallowing in alcoholism, Terrence finds himself increasingly drawn to the evil portal and the power it possesses.
Terrence breaks into Glen's old house and begins the ritual to summon the demons and grant him the power to get his father's life back on track. He is interrupted by three other teens who also broke into the house. While John and Moe are content to ridicule Terrence, John's girlfriend, Liz is extremely interested in demonology and convinces her two friends to join Terrence in completing the ritual. Terrence summons a Minion (one of the small creatures that ran amok previously) through the Gate. In a panic, John pulls out his revolver and shoots it, then storms off with his friends in tow. Alone, Terrence retrieves the Minion's body and takes it home. It survives, so Terrance opts to keep it in a cage as a pet.
The next day, Terrence finds that his wish has seemingly come true. His father, once a proud airline pilot, has given up the bottle and netted a job flying for a major carrier. When Liz comes over later, they discover they can use the Minion to grant any wish they want, but with dire consequences.
Liz burns an effigy of her car pin to make a real one, and John and Moe create money and go pigging out at a fancy restaurant after stealing the minion and trashing Terrence's house. The minion gets loose and attacks the boys, infecting them both.
John and Moe have metamorphosed into demons. They kidnap Liz to sacrifice her. Previously Liz and Terrence imbued an old jewelry box belonging to his mother as a vessel of light to destroy the darkness.
Terrence is brought to the dark world, greeted by the demonic John and Moe and given the task of killing Liz to complete darkness after metamorphosing into a demon as well. Terrence fights for himself, to save Liz and hurls the box into the gate. It explodes with light and they are transported back to Earth. Terrence dies.
After the funeral service for Terrence ends, he emerges from the coffin and Liz and Terrence kiss. After they leave, John and Moe also emerge from the coffin. Seeing Liz and Terry together, they state, "Who needs chicks, when you got demons!" It is revealed after the credits that Terrence's hamster, that had been sacrificed by John to open the portal has also been brought back to life and exits the coffin.
