Claire is as independent and strong-willed as she’s ever been. Claire faces a host of new dangers and adventures in the New World as she strives to make a permanent home alongside Jamie in the 18th century. And being a woman out of time continues to be a hurdle for Claire, who must suppress her desire to change history, knowing it can’t be done, and focus on what is within her control — making her corner of the world a better place. Even though her relationship with Jamie is stronger than ever, Claire can’t help but be plagued by memories and thoughts of her cherished daughter, Brianna, whom she left behind in the 20th Century.

We find Jamie Fraser being seduced by the breath-taking, promise-filled and treacherous land that is Colonial America. While danger and uncertainty are not new territories for Jamie — there is more at stake for him with Claire at his side. He’s lost her once; he wouldn’t be able to survive losing her again. Jamie does his utmost to provide a future for himself and Claire, but the search for a place to call home proves more difficult than he anticipated. After many hardships and false-starts, Jamie manages to build a home he is proud of, becoming the successful landowner he’s always dreamed of becoming — a role model for all pioneering men.

Strong-minded, stubborn, and intelligent beyond her years — traits inherited from her mother, Claire and nurtured by the father who raised her, Frank — Brianna embodies the 1970s American woman. It’s her independent spirit and self-sufficiency that her boyfriend, Roger Wakefield, finds compelling… and maddening. When Roger expresses his desire to spend the rest of his life with Brianna, she admits that she isn’t ready for a life-long commitment. While she knows she loves Roger, her parental role models, Frank and Claire, did not represent an ideal married couple and have left Brianna uncertain about the longevity of romantic relationships. As Brianna tries to navigate her complicated relationship with Roger, she comes across research in the 20th Century that sends her travelling back in time to the 18th Century in an effort to rescue Jamie and Claire from a grave fate.

Roger is Reverend Wakefield’s adorable adopted son, an intelligent, charming and proud Scot who is hopelessly in love with Brianna Randall. He has their life together all planned out — they’ll marry and live in England, where he’ll continue working as a historian at Oxford and eventually have children and raise a family together. But Roger’s dreams are jeopardized when Brianna’s mixed feelings about long-term commitment and shared miscommunications between them threaten to derail their relationship. Roger must travel the distance — and time — to prove his devotion to Brianna.

After being rescued by his Uncle Jamie and Auntie Claire at the end of season 3, we find Young Ian thrilled to be in the unfamiliar New World — it holds all kinds of curiosities that he’s never encountered before. He longs for a life filled with new experiences and is inspired by the beauty and Native cultures in the New World. As Young Ian helps Jamie and Claire carve out a new life in America, he takes steps towards blazing his own trail, becoming his own man and ultimately discovers the path he’s destined to take.

Fergus, Jamie’s adopted son who grew up in a French brothel, has grown into a charming and devilishly handsome man. Under the influence of Jamie as a father figure, Fergus has developed a strong sense of loyalty and decorum, despite his unconventional upbringing. While he’s happily married to Jamie’s stepdaughter, Marsali, his new role as husband and father are not without their challenges. He’s no longer under Jamie’s protective wing and must provide for his family on his own, which proves to be more difficult than he anticipated. Fergus struggles to prove his worth to himself and his growing family.

Marsali is the high-spirited and outspoken daughter of Laoghaire MacKimmie Fraser, the woman Jamie married in Claire’s absence. While she shares some of her mother’s traits — rebellious and outspoken, she differs from Laoghaire in that she’s fallen in love with a man who loves her in return — Fergus. Their marriage is rather unconventional for their time, Marsali speaks her mind and bravely faces down the challenges that life in the New World presents, characteristics that Fergus can’t help but cherish. In season four, Marsali endeavors to make a happy life for her burgeoning family in the New World.
