His family targeted by a vengeful crime boss in Istanbul, retired CIA agent Bryan Mills (Liam Neeson) must fight an army of killers to ensure their safe return in this action sequel from director Olivier Megaton (TRANSPORTER 3) and producer/co-writer Luc Besson (who penned the screenplay alongside TAKEN scribe Robert Mark Kamen). As the families of the kidnappers killed by Mills gather together for a mass funeral, their leader Merad (Rade Sherbedgia) vows to make the man who brought them so much misery pay. Meanwhile, back in the U.S., Mills invites his ex-wife Lenore (Famke Janssen) and their daughter Kim (Maggie Grace) to join him on a trip to Istanbul after their long-planned trip to China falls through. Later, in Istanbul, the family is settling in and enjoying the sites when Merad's gang abducts Mills and Lenore. Communicating with her father via a hidden mobile phone, Kim accesses his secret weapons cache and embarks on a frantic race through an unfamiliar city in a bid to rescue her parents from certain death. Once she manages to free her father, Mills puts his 'particular set of skills' to use while attempting to rescue his Lenore, and escape Merad's unrelenting attack.
