While the Lazarus team is trying to find its way back to 2012, Janet is already there, hard at work with Dr Gray. After being sent back to 2012 against her will, Janet has been tasked by the mysterious Time Break Initiative to fix the faulty time machine and ensure it won't cause the three-week loop in the future. With only her daughter, Becky, and her intimidating bodyguard, Bryson, for company, Janet gains the trust of Gray as they work together to develop the time machine. With the opportunity to rewrite time, will Janet try to prevent Dr Gray's impending assassination? And how will she view the part played by the Lazarus Project - and herself - in the tragic events that are to come?

When a catastrophic event severely compromises the Lazarus team's plans, George and Sarah must work together to execute their mission and are forced to go head-to-head with an unyielding Wes. Just when it's looking as though their entire mission has been futile, the pair realise that they have one last bargaining chip. But will they use it if it means abandoning their morals? And can George come to terms with the reality that he may not be the good guy after all?
