Nikki Bratchett (Brooke Davis) is a villainess from the 2002 TV film Second to Die. She was the daughter of explosives expert Jim Bratchett and the stepdaughter of his second wife, Sara Morgan Bratchett, her having come to live with them after her mother committed suicide. Nikki was wheelchair-bound and mentally disabled, with Sara growing frustrated with having to care for her without any help from Jim.
However, as revealed in the film's conclusion, Nikki was not only ably bodied, but she was actually Jim's lover and was colluding with him, Raymond "Scooch" Scucello, and Cynthia Evans to make off with Jim's two million dollar life insurance money (which he'd placed in a "second to die" insurance policy). To do so, Raymond and Jim faked Jim's death by having Raymond begin an affair with Sara and go along with her plan to kill Jim. Jim later called Sara and claimed that Raymond was trying to kill her, leading to Sara seemingly being shot to death by investigating Detective Grady as she tried to shoot Raymond.
The film's conclusion had Nikki meeting up with her cohorts and sharing a passionate kiss with Jim, revealing herself as his lover and partner in crime. But as the gang marveled at their ill-gotten money, Grady and Sara entered the house, revealing that the two had faked Sara's death to catch the con artists. They then agreed to let them all walk free, under the condition that they leave the money behind. Nikki and her cohorts begrudgingly agreed and fled the scene.
