Leprechaun 2

In 990s Ireland, the leprechaun celebrates his 1,000th birthday, on Saint Patrick's Day. The leprechaun's intends to marry his slave. In response to her father William O'Day's pleas, the leprechaun says that she will be his only when she sneezes three consecutive times without anyone saying "God bless you". He manipulates her to start sneezing. O'Day says "God bless you" to save her and is killed by the leprechaun, who promises to make a bride out of a descendant of O'Day on his next 1,000th birthday.
On St. Patrick's Day, in 1990s Los Angeles, a young man named Cody works with his Uncle Morty giving "dark side" tours, a scam that drives tourists around to the alleged gravesites of celebrities. Cody takes over the tour one day, when Morty is too drunk, forcing him to cancel a date with his girlfriend Bridget, a modern descendant of the O'Day bloodline. The leprechaun emerges from one of the tour stops. He attacks and pulls out a homeless man's gold tooth before leaving in search of Bridget. Cody speeds through a red light and is arrested; Morty bails him out of the police station.
Menawhile, a man named Ian tries to force his way inside Bridget's place to seduce her, but she punches him. While leaving, Ian sees Bridget gesturing for him to come to the garage; however, it is a trick by the leprechaun, who has disguised a lawn mower as Bridget. As Ian attempts to kiss "Bridget", the lawn mower slices him to death. Cody later visits Bridget and gifts her with flowers, and they reconcile. The leprechaun begins to make her sneeze. Cody attempts to say "God bless you", but a phone cord starts to strangle him before he can finish the phrase. The leprechaun then manifests to claim Bridget. After a scuffle with Cody, the leprechaun escapes with Bridget, but loses one of his gold coins after Bridget knocks a pot of gold from his hands. The coin falls into Cody's possession.
The leprechaun takes Bridget to his lair, but realizes a coin is missing. Meanwhile, Cody is considered a prime suspect in Ian's death and Bridget's disappearance. At his house, the leprechaun attacks, demanding his coin back. Morty saves Cody, and they escape to a bar. However, the leprechaun appears there. Morty challenges him to a drinking contest. Morty wins, but the leprechaun escapes, sobering up at an espresso bar and murdering the barista who mocked his height. Noting the leprechaun's weakness for cast iron, Cody and Morty go to a go-kart track office to empty the safe, which is made of cast iron, to capture the leprechaun inside.
As the leprechaun attacks Morty, Cody traps him inside the safe. However, Morty then locks Cody in a supply closet and demands three wishes, in keeping with the tradition. Morty first wishes for his pot of gold. The wish is vaguely granted, the gold manifesting inside Morty's stomach. The leprechaun says that he can remove it if Morty uses his second wish to free him from the safe. For his third and final wish, Morty wishes for the gold to be removed, which the leprechaun grants by disemboweling and killing him. Cody flees the closet, but is apprehended by the guard, who accuses Cody of being behind all the murders. The leprechaun then runs over a security guard with a go-kart. He attempts to kill Cody, who discovers that possession of the gold makes it impossible for the leprechaun to harm him. He enters the leprechaun's lair in search of Bridget.
There, Cody frees Bridget. They attempt to escape the labyrinth-like cave, but get separated. Cody finds Bridget, who asks Cody to give her the coin. He complies and she is revealed to be the leprechaun in disguise. The real Bridget reappears and begs the leprechaun to spare Cody. However, the leprechaun forces Cody to stab himself with a cast iron stake. Cody's death is a ruse (he knew of the trick), as he actually gave the leprechaun a chocolate coin. Still immune to harm, Cody stabs the leprechaun with the stake, causing him to combust. Cody and Bridget escape, discard the coin and kiss.
