Fiona Yu, a 30-ish Chinese-American lawyer, appears to be just another Hello Kitty stereotype. She’s anything but. She says, "I hate Hello Kitty. She’s just clawless, fangless, voiceless, with that placid, blank expression topped by a pink ribbon. I want to be able to pay for my Jimmy Choos myself and tell anyone who tries to put a damn bow behind my ear to go to hell."
To buck her family’s marriage pressure and restrictive cultural tradition Fiona sets out to take her own virginity and by chance reunites with her long lost childhood friend, Sean, who has changed his name and reinvented himself as a respected plastic surgeon, specializing in female genital reconstruction. After their chance meeting, Fi and Sean have a first “date” to catch up. We learn of Fiona’s "Androgynist" nature and get a hint of Sean’s dark side.
While trying to avoid the "nice Chinese boys" her father tries to set her up with and navigate the murky waters of San Francisco’s legal world, Fiona tries out a new life with Sean which consists of fun but platonic dates that always seem to result in dead bodies. Fiona is laid off from her job law firm. Sean takes her out on another “date” and uses his lethal talents to help her into a new position at a new firm.
Fiona's father dupes her into an engagement to the spoiled son of a wealthy chef. Her world starts to spiral out of control as she battles her bullying new boss, her unacceptable new fiancé and Sean pulling her farther outside her comfort zone. Fiona flees and heads to the office to seek sanity only to have her domineering boss abuse her. Fi is forced to fight back using Sean’s methods as inspiration.
And so with Sean’s help, Fiona embarks on a darkly twisted journey of self- discovery and creates her own version of the American Dream, eliminating, without fear or remorse, anyone and anything that stands in her way. Hello Kitty Must Die is a manifesto of Asian feminism, Joy Luck Club meets Dexter.
