The fifth season of the show will launch in the US on 16 February, and while no UK launch date has been announced, if the show follows previous patterns it will likely release on Amazon Prime the day after the US premiere.
That means that Season 5 of Outlander is likely to be available on Amazon Prime in the UK from 17 February.
But if you've been left confounded by four seasons of bodice-ripping time-travelling nonsense, let us get you back up to speed ahead of the fifth series.
Here's all you need to know:
What happened in Season 1?
It's 1946, and former World War II nurse Claire Randall and her husband Frank are visiting Inverness when she's whisked back to 1743 through the Craigh na Dun standing stones.
In the 18th century, Claire falls in with a group of rebel Highlanders who are being pursued by English redcoats led by Captain Jonathan "Black Jack" Randall, Frank's ancestor.
Claire marries Highlander Jamie Fraser out of necessity, but they quickly fall in love. When the Clan suspect her of being a spy, they retain her as a healer, preventing her from attempting to return to her own time.
With her knowledge of the future, Claire tries to warn the clansmen against pursuing a Jacobite rebellion. Among al this, Jamie is captured and tortured by the sadistic Randall, but Claire and his clansmen rescue him.
Claire tells Jamie that she is pregnant, and they leave to sail to France.
What happened in Season 2?
In Paris, Claire and Jamie try to thwart the Jacobites by subverting the funds that King Louis XV of France is likely to provide.
Randall reappears in Paris, but Claire makes Jamie swear to keep him alive until Frank's descent is assured.
She achieves this by convincing Randall to marry Mary Hawkins. Claire loses her baby, and she and Jamie return to Scotland. The Jacobites win the Battle of Prestonpans.
Before the Battle of Culloden, Jamie convinces Claire - now pregnant again - to return to the 20th century, but Jamie would rather die fighting with his clan.
Back in her own century, Claire tells all about her time travel to Frank, who asks her to forget Jamie and let him raise their child as his own.
Claire takes her daughter to Scotland, where she discovers that Jamie did not die at Culloden, and vows to return to him.
What happened in Season 3?
Jamie kills Randall at the Battle of Culloden, but is gravely injured in the process. An inmate at Ardsmuir prison, he befriends the governor, who paroles him to work at an English estate.
There Jamie has an affair and fathers an illegitimate son, before returning to Scotland and becoming a printer.
Back in 1948, Claire enrolls in medical school as she and Frank raise Jamie's daughter Brianna in Boston, Massachusetts. Frank is killed in a car accident while Brianna is in college.
During a trip to Scotland with Brianna, Claire learns some clues to Jamie's fate after Culloden, and returns to the 18th century to find him.
She discovers that Jamie married a widow, and her return nullifies their union, as it is illegal. Jamie and Claire try to retrieve some hidden treasure so that he can placate his new wife with a settlement.
But during this effort, Jamie's nephew is captured by pirates and taken to the Caribbean. Jamie and Claire follow, and manage to rescue him, before setting sail for Scotland.
Along the way, they are shipwrecked on the coast of Georgia, then a British colony.
What happened in Season 4?
In North Carolina (then also a British colony), Claire and Jamie work to find a way to return to Scotland.
They visit the plantation of Jamie's aunt Jocasta Cameron, where they see conditions of enslaved African Americans firsthand.
Claire and Jamie decide to make a new life for themselves, and claim a piece of land they call Fraser's Ridge, though tensions rise with a local Cherokee, who owns the land.
After learning her parents will die in a fire, Brianna goes to Inverness and travels through the stones herself, and is followed by Roger, a man who had previously proposed to her, but had been rejected.
Roger and Brianna meet in Wilmington, North Carolina and quickly enter into a handfast marriage; Brianna finds her parents, but later discovers she is pregnant, having been raped by Stephen Bonnet, the man who had captained Roger's voyage across the Atlantic.
Roger goes to Fraser's Ridge, but Jamie wrongly assumes that he was the one who had raped Brianna and beats him; Roger is then sold to a Mohawk as a captive.
Realising the mistake, Claire and Jamie set off to rescue Roger, who is reunited with Brianna at Jocasta's plantation.
What will happen in Season 5?
We can expect the storyline to more or less follow that of The Fiery Cross, the next book in Diana Gabaldon’s series, and we can expect the Frasers to be involved in the American Revolutionary War if the story follows the drama of the book.
The image used to announce the new season on Outlander’s social media channels saw Jamie, Claire and Brianna looking nervous; Jamie had blood splattered on his cheek.
The synopsis for The Fiery Cross says that Claire’s “unique view of the future” has brought Jamie both “danger and deliverance in the past”.
“Her knowledge of the oncoming revolution is a flickering torch that may light his way through the perilous years ahead—or ignite a conflagration that will leave their lives in ashes…” it continues.
“As Claire knows all too well, friends, neighbours and countrymen are unwittingly marching towards Revolution," says the official synopsis for Season 5 on Starz, "with members of the elite ruling classes struggling to stifle the alarming undercurrent of unrest triggered by the Regulator Movement.
“Against this backdrop, which soon heralds the birth of the new American nation, Claire and Jamie are forced to ask themselves just how far they are willing to go to protect their home, and praying there will be no reason to light the fiery cross, an ancient Scottish call to arms.”
