The film stars Mary Elizabeth Winstead, Miku Martineau, Woody Harrelson, Tadanobu Asano, Michiel Huisman, Miyavi, and Jun Kunimura.

The film follows Kate (Winstead), an assassin, whose mentor and handler (Harrelson) assigns her to kill a high-ranking yakuza boss.

After she was left orphaned as a child, Varrick raised her as a father figure, giving her extensive training in weapons and combat and eventually inducting her into his private team of wetwork specialists.

While Kate's assignment is a success, this breach of her personal code to not kill in the presence of children leaves her in emotional turmoil.

Kate tracks down Stephen and his girlfriend and learns that they were strong-armed into poisoning her by Sato, a yakuza affiliated with the Kijima crime family.

Kijima, aware that Kate is close to death, joins her with a small army of his men in launching an attack on Renji's headquarters.

In October 2017, Netflix acquired Umair Aleem's script Kate, with David Leitch, Kelly McCormick, Bryan Unkeless and Scott Morgan producing the film.

The website's critics consensus reads, "Mary Elizabeth Winstead does reliably gripping work in the title role, but Kate is disappointingly derivative of numerous other female assassin films.

[16] The Hollywood Reporter review of Kate criticizes it as a derivative film lacking originality, and a mishmash of other action flicks, such as Extraction, Gunpowder Milkshake, and John Wick.

[17] Likewise, Teo Bugby of The New York Times criticized it as an unremarkable and clichéd, in particular feeling that the film's portrayal of Japanese culture and aesthetics was shallow.
