An American horror film series centered on a djinn, an omnipotent, supremely evil genie entity who is released from a jewel and seeks to capture souls.
A narrator (Angus Scrimm) explains that when "God breathed life into the universe…the light gave birth to Angels…the earth gave birth to man...the fire gave birth to the djinn, creatures condemned to dwell in the void between the worlds." If a person wakes a djinn, that person will receive three wishes but the third wish will free legions of djinn on Earth. In 1127, the djinn (Andrew Divoff) asks a Persian emperor to make his second wish. When the emperor wishes to see wonders, the djinn uses his powers to torture and mutilate people in the palace. The emperor is horrified, but the djinn tells him to use his third wish to set things right. Before the emperor can make his third wish, Zoroaster (Ari Barak), a Magician (fantasy), explains the consequences of the third wish and reveals a fire opal, which pulls the djinn inside and traps him.
During an attempted robbery of a museum, the fire opal that contains the Djinn is accidentally released by a stray gunshot. One of the burglars, a young woman named Morgana Truscott (Holly Fields), steals the gem and is forced to abandon her partner during the escape. The Djinn escapes and kills the remaining burglar when he accidentally wishes he'd never been born. As the police enter the museum, the Djinn finishes forming into full size, revealing the Djinn (Andrew Divoff). The Djinn assumes his Nathaniel Demarest persona and surrenders to the police. Demarest is put in a holding cell, where he kills a fellow prisoner who wishes to get out the cell. Meanwhile, Morgana has been having dreams were sees glimpses of the Djinn in his true form. Later Morgana goes to Church to visit the priest tending the church, a man named Gregory (Paul Johannson), a former lover of Morgana's. In prison, Demarest is confronted by Butz (Rhino Michaels) and his two henchmen, the Tiger brothers (James Kim and Simon Kim). Butz runs all "underground business" at the prison, and gives Demarest a "friendly" warning that he is going to be watching him. Eventually they meet again, with Butz wanting to join forces with him, but Demarest rejects the offer. Soon after, he asks for drugs that can waste him dead, which is then granted by Demarest controlling the Tiger Brothers to beat him to death, while he does nothing in his own defense. Soon Demarest is temporarily sent to solitary for being a suspect in the murder.
For the third time, the evil Wishmaster returns to wreck the lives of more innocents. This time, his victim is a beautiful, innocent and studious teenage girl named Diana Collins who accidentally opened up the Djinn's tomb (a strange box with a jewel inside) and released him. After gaining his freedom, the Djinn is asked by Professor Barash to let him be the one who makes the wishes. The professor wishes for two of the world's loveliest ladies to be in love with him.
As in the previous films, an evil genie is released from his prison - an ancient jewel - and must grant three wishes to the person who awakens him, in order to release the race of Djinn from Hell and allow them to take over the earth.
