When a mission goes awry, Wyatt and Rufus are forced to bring a 17-year-old John F. Kennedy with them to the present. Anxious to return the future president to history, the team must find a way to work together to rescue JFK and return him to the past before Rittenhouse assassinates him in 2018.

When Rufus and Jiya add a fourth seat to the Lifeboat, for the first time ever, Connor Mason joins the team as they travel back to the dusty backroads and smoky juke joints of the Depression-era South to rescue the life and legacy of Robert Johnson – King of the Delta Blues, Godfather of Rock n’ Roll and a man who, legend has it, bought his musical genius from the Devil for the price of his soul. Meanwhile, Agent Christopher keeps Wyatt in the present to execute a dangerous raid on Rittenhouse headquarters.

In the bustle of 1919 New York City, suffragette Alice Paul is framed for murder and the Time Team partners up with legendary female crime solver Grace Humiston – AKA “Mrs. Sherlock Holmes.” Together they attempt to prove Alice’s innocence in time for her to give a powerful speech that turns the tide in the passage of the 19th Amendment giving women the right to vote. Back in the present, Connor Mason salvages key intel from the Rittenhouse raid.

The Time Team travels back to 1981 Washington D.C. on the day President Reagan was shot, only to discover that the Sleeper’s target isn’t the President – but a young rookie police officer – none other than Agent Christopher, who brought the time team together and kept the Lifeboat from getting into Rittenhouse’s hands. The Time Team must save Agent Christopher’s life and prevent her from making a mistake that set her on a different path that would forever change her own future, the future of the team -- and the future of the world.

When the Mothership jumps to South Carolina in 1863, the Time Team partners up with a courageous Union spy and military leader, Harriet Tubman - AKA "The General" - to thwart Rittenhouse's plan to alter the outcome of the Civil War. Back in the present, Rittenhouse hits the team where it hurts the most. Then, Jiya makes a daring escape from Rittenhouse that strands her in San Francisco's Chinatown in 1888 with no way home.
