Amber is a dissatisfied manager at Tuscan Grove, an Italian chain restaurant in Bakersfield, California. After being recommended by her boss, Paul, Amber receives an all-expenses-paid trip to Italy to participate in Tuscan Grove’s special management program, as well as an opportunity to meet the company’s charismatic founder and CEO, Nick Martucci. Her friend Emily is excited for her trip, predicting that she will find love. Amber travels to Italy and meets program supervisor Craig, who takes her passport as well of those of the other managers on the trip. Despite the rustic images shown online, the accommodations consist of a company-owned motel, and members of the program - women Deb, Susie, and Jen, and men Dana and Fran - are told they cannot leave the property without permission. The group begins learning lessons about food from chef Liz Bence, who designs the Tuscan Grove menu. One such session is interrupted by the arrival of Nick, along with his assistant Kat. Nick reacts strangely upon meeting Amber, telling her that she resembles his late sister.
Kat pulls Amber out of the lesson and invites her to a bar in Lucca; however, the plan is overheard by fellow group member Deb, who then shares it with the other managers, turning the planned outing into an evening at the ‘bar’ on the Tuscan Grove campus. The following morning, Kat wakes Amber up early and drives her to a yacht, where Nick is waiting. The two have an intimate conversation and eventually kiss. At the end of the day, Nick invites her to a party the following night, and cautions her not to tell the rest of the group what has happened, to avoid accusations of favoritism. The next day, Amber is escorted by Kat to the party in Rigoli, where she is flirted with by multiple attendees. After sharing a dance with the host Ricky's son Giorgio, she is accosted by his lover, and is pulled away from the party and taken to a club by Kat. The two kiss, but Amber stops them; Kat tells Amber that Nick is selfish, and that Amber is not the only woman that he has done this with. Amber awakens the next morning in the van Kat drove her in, but Kat is nowhere to be found. Later that day, she sees Kat driving off in the van with Susie.
Susie is not at the session the following day, and Jen soon excuses herself, leading Amber to share her suspicions that something is not right on the trip with fellow manager Dana. Dana suggests that Nick is the mastermind, but Amber refuses to believe it, putting the blame on Kat. Dana sneaks into the office on the campus and finds pictures of former members of the program, almost all of whom are women. He speculates that he and Fran were chosen because their names caused them to be mistaken for women. Amber sees Nick leaving the grounds with Jen and follows them in the van, confronting Nick at his yacht. Nick accuses Amber of trying to push him away, and reveals that he has fired Kat, calling her unstable. Amber and Dana demand their passports back from Craig, who encourages them not to ‘rock the boat’. After Nick arrives during an impromptu group game of Mafia the next day, Dana confronts him about his impropriety. Nick breaks down, saying that he envisioned Tuscan Grove as a high-end restaurant, only for it to turn into a fast casual chain. In the evening, Dana sneaks out to a party at Nick’s on-site villa, where he sees men with automatic weapons entering. He returns with Amber, and they see Liz Bence, who has not been seen in several days, bound and gagged inside. Dana leaves to rescue her, but is heard screaming. When Amber arrives, she finds Deb kneeling over his unconscious body. She returns to the motel and gets Fran; the two of them discover what appears to be Jen’s dead body in her bed.
Amber and Fran return to the villa and find a barely-conscious Dana, who reveals that he was attacked by a pack of wild boars. They go into the villa to attempt to hide, but discover an orgy happening inside, attended by Nick, members of his family, Liz Bence, and attendees of Ricky’s party, all filmed by Craig. The party is interrupted as the pack of boars stampede into the house, sending the guests scattering and allowing Amber to call the police. It is revealed that Jen was merely sleeping, not dead, and that Susie took a spontaneous trip to Genoa, explaining her disappearance. The members of the group return home, with Craig reminding them that they have signed a non-disclosure agreement about their experiences. Back in Bakersfield, Nick shows up unexpectedly at Tuscan Grove to ask for Amber’s forgiveness, and for them to continue as a couple . She rebuffs him, and smiles as she returns to her work.
