They may be separated by centuries, but Claire and Jamie's love endures on Season 3 of "Outlander."

A new full-length trailer finds the couple living separate lives. In the 1940s, after returning through the stones, Claire (Caitriona Balfe) reunites with husband Frank (Tobias Menzies), and the two raise her daughter with Jamie, Brianna (Sophie Skelton). But their marriage is troubled, with Frank hurt and angry that Claire still holds a torch for Jamie.

Meanwhile, back in the 1740s century, Jamie (Sam Heughan) is taken prisoner by British soldiers, including Lord John Grey (David Berry) — whom he will eventually befriend.

The trailer also shows glimpses of an older Claire, in the 1960s, with Brianna and her love interest, Roger Wakefield (Richard Rankin), trying to trace Jamie's whereabouts after the doomed Battle of Culloden. "We'll find him," Brianna promises. But when they do, will Claire travel back through the stones to be with her true love?

"Outlander" Season 3 premieres Sunday, September 10 on Starz.
