OnKilling Eve, Eve Polastri (Sandra Oh) is an MI5 agent who plays a game of cat and mouse with the ruthless assassin Villanelle (Jodie Comer). Eve and Villanelle are probably as obsessed with their work (and each other) as Beth is with chess. Plus, there's plenty of gritty ambience and beautiful outfits (hello, Villanelle's pink dress!) to enjoy, too.
