Based on Christopher Reich's espionage novel "Rules of Deception." The thriller focuses on a physician who loses his wife when she falls in a ravine while they're hiking in the Swiss Alps. The grieving doc receives a letter addressed to his wife, learns she wasn't who he thought she was and soon finds himself in the center of a mess that could result in nuclear war in the Middle East. Paramount has franchise hopes for the property. Reich is working on a second installment to the tale.
