LOST: Circle

This mystery-drama revolves around a newspaper reporter named Dan Vasser who suddenly begins to travel through time to change the lives of those around him. When his travels reunite him with his long-lost fiancée Livia, life with his present-day wife gets very interesting.

The Doctor and his companion travel across time and space encountering incredible friends and foes.

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?

When their aspiring scientist friend Barry's invention goes awry, best friends Shelby and Cyd gain the power to leap forward and backward in time whenever they want – and sometimes when they don't. Now, they experience the twists and turns of friendship and must decide between fixing mistakes in the past or catching a glimpse of the future. While Barry and his assistant, Naldo, try to figure out how to replicate time travel for themselves, Cyd and Shelby use their newfound power to navigate high school life and Shelby's mischievous twin brothers, Bret and Chet.
