A burned-out bodyguard is hired to protect the man he hates the most: an international assassin who destroyed his career and ruined his life. Forced to put his personal feelings on hold, the bodyguard must use all his skills and years of experience to keep the assassin alive in the face of constant danger.
A terror is stalking the land: people are disappearing daily, their bodies appearing covered in savage gashes coupled with precise surgical cuts. The legend of the 'Werewolf of Allariz' spreads across the land like wildfire. When Barbara (Elsa Pataky) falls in love with travelling vendor Manuel Romasanta, she is at first besotted with him - but soon begins to be suspicious of him. What has happened to her sister, who - after being escorted by Romasanta to the city - seems to have disappeared forever.
