Revenge of The Billionaire’s Maid: Maddie and Ben's Full Story, Characters & Ending

Hidden behind a curtain during one of Richard's secret meetings, Maddie hears him order the killing of two police officers. Mia catches her near the door and grows suspicious. Meanwhile Ben keeps standing up for Maddie, and years of hidden feelings come out in a kiss in the kitchen.

Mia photographs the picture in Maddie's locket and pays her fixer, Jacob Smith, to identify the man. He was William Reed, a mob boss Richard wiped out. Jacob's questions reach Mark Bennett, a former Reed enforcer who has spent years drinking over the night he failed his boss, and Mark sets out to find the maid with the locket.

Helen then tells Maddie everything. William Reed was a crime boss, and Helen is not her real mother. The night William and his wife Sarah were killed at the mansion, Sarah forced Helen at gunpoint to swap their babies. Helen's own child died with them, and she raised Maddie as hers.

Maddie tells Ben that his father killed hers. Mia and Jacob plant cash and a watch in Maddie's room to frame her as a thief, and Richard plans to get rid of her for good. Ben saves her by pretending to throw her out on the street, then asks his lawyer friend Lisa for help and breaks off his engagement.

Maddie teams up with Mark and Lisa. They need the evidence in Richard's hidden drawer, so Maddie sneaks back into the study, where Richard and Mia are waiting. Richard fires at her, but Ben knocks his arm aside, and a wounded Maddie escapes with the files in the trunk of Ben's car.

Ben and Mark corner Jacob, who admits Richard killed William because William was about to go to the police. Mia lures Maddie into a warehouse ambush, but Ben and Mark arrive in time. Ben lets his father walk away, and Maddie, with Mia at her mercy, lets her go. Then Richard invites Maddie to the mansion to negotiate, and she goes.

Over a glass of whiskey, Richard brags that he killed William Reed and is glad he did. Maddie's phone has been connected to the emergency line the whole time. The police arrive, and Richard leaves his mansion in handcuffs.

Mia isn't finished. She fakes leaving the state, then corners Maddie and Ben in their hotel room with a gun. Mark, worried when Maddie doesn't text him as promised, breaks down the door. He is fatally shot in the struggle, and Maddie knocks Mia out. Mark dies saying that this time he was there to save the Reed family.

At Mark's funeral, Lisa confirms that Richard and Mia have both been charged and will spend the rest of their lives in prison. Maddie leaves her father's locket on Mark's coffin and embraces Helen, calling her mom. Two months later, in the garden, Ben proposes, and Maddie says yes.
