01E01 - Nice Face

MI5 Agent Eve Polastri is assigned to a special task force to protect the only witness of an unknown assassin, presumed by Eve to be the one killing people all over the world. Obsessed with female assassins, Eve has formed an investigative dossier on her own and has connected all to one unknown female assassin. Unbeknownst to Eve, she actually meets her antagonist while on guard duty for the only witness. Failure to save the witness results in Eve being fired by MI5, only to have another opportunity knock on her door for her personal obsession to become a reality. Meanwhile, Villanelle (the assassin) learns of Eve and her new task force. Though warned off by her handler not to touch either, she has the impetus to ignore these orders, as she is quite a psychotic yet brilliant assassin.
