Jacob Fitts, television host and survivalist, with his crew producer Adam Levine and cameraman Mason Riley set out to shoot another episode of their popular survival show, I Am Alone. Episode 413 takes us deep into the Colorado Rockies where Jacob will be left alone for 7 days while his team sets off into town to capture footage and shoot interviews. Within hours a viral outbreak spreads rapidly across the globe. Unaware of this outbreak, Jacob, isolated and alone, continues shooting his television show. As day one comes to a close, Jacob is attacked and bitten by an infected person. As the virus spreads through the town, Mason and Adam have to fight the infected to save their own lives. With the CDC monitoring the outbreak, they pick up Mason and all his footage and bring him back to base for questioning. Reviewing Mason's footage the CDC tries to piece together why the virus has taken longer to transform Jacob. The CDC forces Mason to relive the events of the previous days through his footage to learn more about the virus and Jacobs survival.
