The Lazarus Project team sets out to break the cycle, while a guilt-ridden George is desperate to redeem himself as he embarks on an attempt to win back the trust of his colleagues and Sarah.

The team attempts to track down the time machine that had been used to transport Janet back to 2012, while an unexpected visitor from the past comes looking for George.

When the time machine does not work in the way they had planned, George and the other members of the Lazarus mission find themselves stranded in the wrong year, but they must resist temptation in the past as they work to get back to their present.
