Fantasy Island (2020)

Five people — businesswoman Gwen Olsen, former police officer Patrick Sullivan, stepbrothers J. D. and Brax Weaver, and teenager Melanie Cole — arrive at Fantasy Island, a tropical resort where fantasies apparently come true. Upon arrival, island proprietor Mr. Roarke guides them to their fantasies: Patrick is enlisted in a war in honor of his late father; Melanie takes revenge on her childhood bully Sloane Maddison; the Weavers become honored guests at a mansion rave; and Gwen accepts her ex-boyfriend Allen Chambers' marriage proposal, which she rejected many years ago.

Melanie eventually learns that Sloane was kidnapped and brought to Fantasy Island against her will. She saves her from a masked surgeon and both run away. Meanwhile, Patrick is captured by a military platoon and taken to their commander, Lieutenant Sullivan, whom Patrick recognizes as his father. As night falls, the surgeon attacks Melanie and Sloane again before Damon, a private investigator, kills him. Damon reveals that Roarke offered him to see his deceased daughter, but the fantasy turned into a nightmare that trapped him on the island. He also explains that the fantasies are created by spring water under a glowing rock in a cave. The trio collect some spring water and head back to the resort for help. The next morning, Gwen wakes up to find she has a daughter with Allen and becomes dissatisfied.

When Roarke explains that the fantasies must be fulfilled so that his own fantasy of being with his deceased wife can continue, Gwen convinces him to give her the fantasy she really wanted: to save her neighbor Nick Taylor, who died in a fire. Unknown to the guests, Fantasy Island begins to turn the fantasies into nightmares as the Weavers are taken hostage by a drug cartel associated with the mansion's owner. Gwen is taken to the night she accidentally started the fire that killed Nick and finds out that the other guests, except Melanie, were also there and attempts to save Nick, but fails and is rescued by Roarke's assistant, Julia. Elsewhere, Sullivan's soldiers are summoned to rescue the Weavers; after being shot dead, the cartel reanimate as zombies who attack the soldiers. In the ensuing gunfight, J. D. is fatally shot and Sullivan sacrifices himself so Patrick and Brax can escape back to the resort.

The zombified surgeon ambushes Melanie and Sloane, but Damon sacrifices himself and leaps over a cliff with him. The remaining guests regroup at the resort, but are cornered by Roarke. He reveals that they are in a fantasy in which they are all killed. Realizing that everyone was involved in Nick's death—Melanie says that Nick asked her out that night and she turned him down, which is the reason he was at home—the guests assume it is Julia's fantasy as they believe that she is Nick's mother. The guests escape to the dock to be rescued by a plane sent by Damon's associates, but it is shot down. In response, the guests run to the cave to destroy the glowing rock with a grenade that Patrick is carrying. They enter the cave but quickly become separated and lost. As they wander the cave, they begin to be confronted by the different zombies that have come to torment them. Patrick has an encounter with his father who tries to drown him, Sloane comes face to face with her darker self, and Gwen faces her false daughter and an image of Nick, burned beyond recognition. Gwen apologizes for her actions and asks to be the only one punished for what happened calling out to Julia to free the others. Nick looks confused, asking, "Who is Julia?" Melanie suddenly stabs Patrick and takes Sloane hostage, revealing that it is her true fantasy. She orchestrated the guests' arrival to seek revenge on them for Nick's death, with whom she had a date and was convinced he was her soulmate. Julia is revealed to be Roarke's wife, brought back to life by the island's powers after dying of a terminal disease from which she was suffering when she met Roarke, and convinces him to help the guests before disappearing.

Sloane remembers the spring water she collected before and wishes Melanie to be forever with Nick. As a result, Nick's zombified corpse attacks Melanie and drags her into the water. Before drowning, Melanie activates the grenade, but Patrick sacrifices himself and falls on it to protect the others, paying tribute to how his father died years ago. As the fantasy concludes, Gwen, Sloane, and Brax wake up at the resort, where Roarke agrees to let them go. While the guests board a plane to leave the now-purified Fantasy Island, Brax wishes for J. D. to come back to life. Roarke explains that Brax must stay on the island for the fantasy to come true. After Gwen, Sloane, and a resurrected J. D. depart, Roarke asks Brax to become his new assistant. Remembering a nickname J. D. gave to him while they were at college, Brax chooses to rename himself "Tattoo".
