Two years ago, retired CIA agent Bryan Mills (Liam Neeson) used his ``particular set of skills'' to rescue his daughter, Kim (Maggie Grace), from kidnappers. Since then, Kim has been learning self-defense from her father, and Bryan has been on a personal mission to reunite with his ex-wife (Famke Janssen) . In Istanbul, Bryan and his family cross paths with Murad (Rade Serbedzija), whose son died at Bryan's hand during Kim's rescue. Murad wants revenge, and he'll stop at nothing to get it.
