Savers

Jacob Smoot is, what he thinks, a regular 28 year old man just beginning to figure out what life is. He has a beautiful girlfriend and a steady job. He was in a "unexplained" accident when he was 20 and can't remember his life before, but he's now content with what he has. While on a business trip in Seattle, Washington, he walks into a restaurant and passes 6 people who stare at him as he passes by. Being paranoid, he immediately walks out, but only to find all 6 of them surrounding him. They tell him that he was the President of a secret time traveling organization called "Savers" years ago.  The 6 people explain that they are the team leaders within the organization and how they thought he was dead when he was abducted from the "Takers" 8 years ago. They Savers couldn't function without him and shut down the organization, leaving the world to potentially self-destruct. The leaders ask him to restart the organization to fix the past and future world that the Takers have destroyed. 
Can he trust the 6 people?
Would he be willing to leave his perfect life to believe in the Savers?
With his memory loss, will he be able to handle the risks of the Savers Organization?
