Scientist Ellie Ward has discovered a portal to the past. In fact, she discovered it at her childhood home when she was nine and she's been using it to extract herself from bad situations ever since. Each time it's returned her to the 'defining moment' in her past - the point in time where a bad decision set her on the path to tragedy. The problem is, Ellie never knows what her defining moments were and so she never has any idea how much of her life she's going to have to repeat to avoid her latest ordeal. When Ellie's research takes her to a remote area of northern Canada, she faces yet another crisis when her small plane crashes in the bush. Seriously injured and stranded more than 2000 miles from her window to the past, this time Ellie has no way to rewind the clock.
