NBC canceled bubble drama "Timeless" after one season, but three days later surprised fans by renewing the series for a second season consisting of ten episodes.

'Timeless' plotline

"Timeless" is a science fiction adventure series about three strangers that team up to go back in time when an experimental time machine is stolen. The culprit, Garcia Flynn, travels back to famous historical moments with the intent to change the present and stop a mysterious organization called Rittenhouse. History professor Lucy Preston teams up with scientist Rufus Carlin and soldier Wyatt Logan to stop Flynn.

Meanwhile, Lucy struggles with the loss of her sister that is written out of history after the team travels back to the Hindenburg disaster, 1937. Wyatt is still mourning the death of his wife and plans to use the time machine to prevent it, as Rufus is blackmailed by Rittenhouse to spy on Lucy and Wyatt. As they travel through history they meet a wide range of famous figures such as "James Bond" author Ian Flemming (Sean Maguire), Eliot Ness (Misha Collins), and Bonnie (Jacqueline Byers) and Clyde (Sam Strike).

The series stars Abigail Spencer as Lucy, Malcolm Barrett as Rufus, Matt Lanter as Wyatt, Sakina Jaffrey as Special Agent Denise Christopher, Paterson Joseph as Connor Mason, Claudia Doumit as Jiya Marri, and Goran Visnjic as Garcia Flynn.

Susanna Thompson to be a Big Bad

The cast of "Timeless" and co-creators, Eric Kripke and Shawn Ryan came together for San Diego Comic Con to tease season two, beginning the panel by celebrating and thanking the fans for the renewal. The writers won't get together until September so nothing is official, but they teased plans for Susanna Thompson.

The season one finale revealed that Lucy's mother, Carol (Thompson) is a member of Rittenhouse, and will step up as a Big Bad for season two. Lucy, Wyatt, and Malcolm will find themselves allying with Flynn as they come up against Rittenhouse as a common enemy. Matters will be worse than before as Rittenhouse now has a time machine on their side.

More untold history to come

The second season of "Timeless" will be doubling the untold history similar to the stories of season one, going further into race, gender, and other ignored players in history. Eric Kripke shared that he believes "history is for everybody, and America is for everybody." Despite the shortened season, Kripke and Shawn Ryan are glad to receive a smaller episode order from NBC, describing the series as one that is hard to do in 22 episodes. The ten episodes will feature a more compact story. Kripke added that it is unlikely that "Timeless" will travel to the future, as he considers the show a historical adventure rather than a science fiction drama.

"Timeless" season two will premiere at midseason in 2018 on NBC.
