The unnamed Brunette Seductress was a villainess from the 2011 film Deadly Attraction (alternately titled 365 Days). She was a woman who encountered Trigger (a friend of the film's primary antagonist, Mark Fisher) at a club, inviting him to a hotel for a tryst.
Unbeknownst to Trigger, however, his date was the scheming cohort for a closeted gay man, who paid her to seduce men he picked and lure them back to the hotel so he could forcibly have sex with them. Once at the hotel room, the brunette turned heel by giving Trigger a drink laced with drugs, and convinced him to let her blindfold and handcuff him before leaving him to be raped by her cohort. Afterwards, a young boy came to release Trigger from his bonds, revealing that the villainess paid him $10 to do so.
Trigger later confessed to being raped to Mark, who promised to kill the seductress if he ever saw her again. Sometime later, while Mark and Trigger were at a party with their friends, Trigger recognized the woman dancing with their friend Killer as the same woman who set up him to be raped, leading to his friends confronting her, repeatedly slapping her until she confessed to her crimes; doing so after making threats to kill the men. After her male cohort was dragged outside, Mark pulled out a gun and shot the man dead, horrifying the brunette. Despite her pleas to be spared, Mark went through with his earlier promise and killed the villainess with a shot to the head.
