Timeless

NBC, 10 ET/PT

They're back, if you can believe it. Thanks in no small part to a devoted fan campaign and USA TODAY's Save Our Shows poll, Timeless returns for a second season on NBC tonight after being canceled by the network last year, and Wyatt (Matt Lanter), Rufus (Malcolm Barrett) and Lucy (Abigail Spencer) aren't wasting any time. Wyatt and Rufus chase the Mothership France in World War I to rescue Lucy, who has been taken by the Rittenhouse organization. But she's been busy recruiting Marie Curie (Kim Bubbs) to help save a wounded soldier.
