Task: Question Answering
Input (English): Passage: The film begins with self-help author Wes Wilson who has recently come out with his first best selling book. At the after-party, he meets up with an attractive woman named Samantha. They flirt, and he proposes publicly.  He introduces her to his agent, who tries to talk Wes into writing a sequel.  Wes dismisses the agent and takes Samantha to his car to leave the party early.  They are attacked in the parking lot, and Samantha is knocked out and kidnapped.
Time passes slowly for Wes, who is haunted by his inability to save her. At a book signing, however, Wes also encounters Nicole, a young woman who says she is a reporter. He goes to her house for an interview, and they bond, and he enters into a relationship with her. A few more months pass and Wes and Nicole become a happy couple.
Suddenly a mysterious man named Isaac who Wes had met before at the book signing, shows up and demands to know where some diamonds are. Wes runs away, and Isaac's main henchman Boone and another give chase. Wes is kidnapped as a result along with Nicole and Isaac orders him to go to some bank and empty the contents of a safety deposit box which could be the diamonds themselves. Wes finds a briefcase and then he and Nicole are released. To Isaac's surprise, there is only a stuffed toy in the briefcase and he resumes his hunt for the diamonds.
Eventually, Wes gets back to his apartment, only to find Samantha there to his shock and surprise. She apologizes and tells Wes she stole the diamonds from Isaac and that Isaac won't stop until they are dead and he has the diamonds but Wes is still heartbroken that she would betray him like that as he felt guilty for not being able to help her and believed that she was dead for so long. Samantha also tells him that Nicole wants the diamonds as well and tells him to meet her under a bridge. Just then, one of Isaac's henchmen shows up, and Samantha kills him after much effort. Wes is frightened, and leaves. 
Question: What is the first name of the person who stole the diamonds?
Output (English): Samantha.
