Season 5

Olivia forces her son Max to consummate a Landgraab heir with Heather to combine the bloodlines. But the alliance between Heather and Olivia gets on thin ice when the Goth family starts to get involved with the conspiracies after the murder of Cassandra Goth. Bella wants to team up with Olivia to take down Heather and get their family fundings back, which were stolen by Nancy years ago. While the residents of Rio Verde start to grow more distrusting of her, Olivia begins to slip further into madness.

Plot
While Olivia is still feeling tense about the shenanigans that happened in Affluista Mansion, the residents of Rio Verde celebrate Winterfest.

Olivia approaches her son, Max, and tells him that he needs to start a relationship with Heather and get a child with her to strengthen the alliance between them. Max refuses however, telling her that he loves Jasper. She becomes frustrated and murders Clement Frost after he visited the house as Father Winter. Later that night, she murders Jasper. Max is sick with grief, but later agrees to have a child with Heather, more out of fear than out of loyalty.

Monica Davies, Theo Dane and Alexander Jamar move into Rio Verde and join the Idiot Roomies. Monica and Olivia quickly become lovers, but Heather suspects that Monica is after the Landgraab money as well after overhearing one of their conversations.

The Idiot Roomies celebrate New Year's Eve at the Blue Velvet Nightclub. Also present at the club is Nina Caliente, one of the household's neighbors who lived in the same house as Cassandra Goth. Olivia, having seen Nina on the night she killed Cassandra, suspects that Nina might have seen the crime and silently murders Nina on the promenade behind the club.

On their way back home, Heather and Monica have some small talk. Heather eventually turns on Monica and shoots her in the head, convinced she is spying on Olivia on the orders of the Goth family, who she believes are after the Landgraab money as well. Olivia griefs her lover and starts seeing her as well as hallucinations. Fearing she might have become wreckless in covering her tracks, Olivia murders Justice Carson, the owner of the food stand on the neighborhood square to prevent him from checking the security camera footage of her murdering Cassandra.

Rumors about Olivia's lethal behavior are spreading in Willow Creek and Oasis Springs. OIivia discovers that Jamir had told his girlfriend, Liberty Lee, about their feud and his suspicions about Olivia. She travels to Willow Creek and confronts Liberty about the rumors. Liberty tells her that Aspen Schafer had told her and Jamir about the massacre at Sander and Daniel's wedding and her suspicions that it was actually Olivia who caused it. Olivia shoots Liberty down, killing her, and travels back to Oasis Springs to go after Aspen. Only her husband is home, so she kills him instead as a warning to Aspen

Heather visits Ophelia Villa to settle the rumors from the Goth family. Bella Goth tells Heather that she knows Olivia murdered her daughter, Cassandra, and wants to team up with her to defeat Olivia. In return Bella promises to forgive Heather and the remaining Landgraab's for the actions of Nancy, who stole money from the Goth's many years before. Heather refuses this offer. She argues with Bella and later assaults her husband, Mortimer. When OIivia visits the Goth family herself, they propose a team-up with her as well. They ask Olivia to kill Heather, in return they will forgive the murder of Cassandra and will help Olivia to get rid of the rumors.

Mei-Lin gets pregnant with her and Louis' baby and Heather gives birth to Carlos Landgraab. Mason gets in a relationship with his high school-sweetheart, Allie Caliente. Audrey, hearing the rumors, suspects that Olivia was responsible for the deaths of James and Jasper. She expresses her suspicions to Alexander. She sneaks into Olivia's room to look at the security footage on her computer, but she gets caught by Olivia, who chokes her to death.

After sharing the bed with one of his clients, Miriam, Theo discovers the crypts and finds a secret room with the the two sugar skulls. Olivia catches him as well and stabs him in the jaw.

Mei-Lin gives birth to Yu-Fei Clayton and invites a few friends and family-members over for a baby shower. Alexander sneaks into Olivia's room to find the security footage. He succeeds and discovers that all the murders by Olivia have been caught on tape. He leaks them onto the internet, just as Olivia bursts into the room and stabs him to death. Realizing she has been busted, Olivia goes crazy. Driven by her rage, Olivia goes on a second muder spree, killing Carl Clayton, Daniel, and Travis Scott. Neighbors Don Lothario and Stetson Caliente overhear the chaos and try to intervene, but Olivia overpowers and kills Stetson. After a fight with Heather, Olivia gets stabbed in the chest by her. While dying, Olivia sees hallucinations of Ben, Jason, Bo, James and Monica, looking down on her disapprovingly. Finally, she sees a hallucination of Mans, seemingly amused as Heather slits her throat.

The following morning, the remaining Idiot Roomies leave Rio Verde for good.
