The team chases Garcia Flynn to 1754, but after he reveals his true intentions, they're forced to scramble through hostile territory. Now, if they want to survive, they'll need to learn to trust each other. Meanwhile, Agent Christopher quietly investigates Connor Mason, and Jiya has a hunch that Rufus might be resourceful enough to open a line of communication with the present.
A mysterious criminal steals a secret state-of-the-art time machine, intent on destroying America as we know it by changing the past. Our only hope is an unexpected team: a scientist, a soldier and a history professor, who must use the machine's prototype to travel back in time to critical events.
While they must make every effort not to affect the past themselves, they must also stay one step ahead of this dangerous fugitive. But can this handpicked team uncover the mystery behind it all and end his destruction before it's too late?
