Much of season one of "1923" revolved around the Duttons' battle to keep hold of their land and cattle. After angering a group of local sheepmen led by Scottish sheepherder Banner Creighton (Jerome Flynn), the family found themselves caught up in a range war.

By the end of the season, Banner had found a powerful ally in mining magnate Donald Whitfield (Timothy Dalton) who found another way to destroy the Duttons.

In the final moments of the season one finale, he showed up at the ranch with a signed document from the bank stating that the ranch's deed would revert to him if Jacob Dutton (Harrison Ford) did not manage to pay his property taxes by the end of the year.

As viewers saw throughout season one, Jacob has no way to pay the ranch's debts, having been denied a loan to purchase more cattle or hay, and is against the idea of taking out a mortgage.

Tragedy struck early on in season one when Jacob's nephew John (James Badge Dale) — who was originally introduced as a child in "1883" as the son of James and Margaret Dutton — was killed in a shootout with Banner and his men.

Beset by grief, his wife Emma (Marley Shelton) shot herself soon after, leaving behind their adult son Jack (Darren Mann) to help defend the ranch with Jacob and Cara (Helen Mirren).

Before the series began, Spencer Dutton (Brandon Sklenar) left the family homestead in Montana to fight in World War I. When the war ended, he chose not to return and instead became a big game hunter in Africa.

He only learned of the peril at the ranch after his traveling companion Alexandra (Julia Schlaepfer) encouraged him to read a stack of unopened letters sent by his aunt Cara.

Once he did, the pair wasted no time in starting their journey back to Montana. He and Alexandra left Kenya via a rickety tugboat that ended up capsizing before being rescued by a cruise liner that took them to Sicily.

Once there, they boarded an England-bound liner, with plans to board another ship to America once there, hoping to make it back to Montana in time to save the ranch.

Without realizing it, Spencer and Alexandra boarded the same ship as Alexandra's scorned ex-fiancé and his aristocratic family.

Tensions built up over the course of the weekslong journey, resulting in Alexandra's former flame, Arthur (Rafe Soule), challenging Spencer to a duel, which Spencer won. Afterward, Arthur pulled a pistol on Spencer, leading Spencer to throw him overboard in self-defense.

As a result, newlyweds Spencer and Alexandra were separated. Spencer made it ashore to the nearest port, and Alexandra vowed to reunite with him in Bozeman, Montana.

Audiences saw another tragedy unfold when Spencer's nephew Jack and his wife Elizabeth (Michelle Randolph) discovered that she had had a miscarriage.

It came after she sustained an abdominal injury during a shoot-out earlier in the season, and it's suggested that this has affected her ability to carry children and continue on the Dutton name.

Alongside Spencer's odyssey to return to the Dutton homestead, the first season of "1923" also focused on the homeward journey of Teonna Rainwater (Aminah Nieves).

Teonna is a young girl from the "Yellowstone" universe's fictional Broken Rock Reservation who has been taken away from her tribe and placed in a residential boarding school run by the sadistic Catholic priest, Father Renaud (Sebastian Roché).

After suffering abuse at the hands of some of the school's nuns, she eventually escapes.

While wandering the badlands, she reunited with her father, Runs His Horse (Michael Spears), and crossed the border from South Dakota into Wyoming. However, a determined Father Renaud wasn't far behind.
