Ozark fans were left on a cliffhanger with that tension-filled mid-series final scene where Ruth Langmore (Julia Garner) left the Byrdes' house in a fury on the hunt for the gangster who had killed her cousin.
It was the scene of the entire show so far for Garner, but left viewers desperate to find out how things would end for the mad-with-grief character and her former bosses Marty and Wendy Byrde, played by Jason Bateman and Laura Linney.
Now, Netflix has announced the date fans need to mark in their calendars - Friday, 29 April – when they will stream the second and final part of season four, which wraps up the Ozark story.
Tweeting a new trailer captioned: "The end is near. Ozark’s final episodes premiere April 29," the clip began with Ruth's final scene from part one where she drove away from the Byrdes with a gun in the car.

She says: "My childhood traumas are not like yours. You see, I’m a cursed Langmore.
"Long inured to violence and death. And in the case of a Langmore, perhaps not soon enough."
The trailer also shows scenes from part one to jog viewers' memories, including a shot of the now-murdered Wyatt, cartel boss Omar Navarro in jail, and Ruth pointing a shotgun at Marty and Wendy.
It ends with the words: "The end arrives sooner than you think," as Ruth is shown sitting in her car looking at the gun.
The last available episode saw Ruth discover that Navarro's violence-loving nephew Javi Elizondro, who has taken over control of the cartel while his uncle is in jail and is suspicious of the Byrdes, had murdered her young cousin Wyatt and his new wife, Darlene Snell, who had refused to shut down her rival heroin farm.
Ruth had decided she had nothing to lose in going after Javi, having lost every member of her family in incidents related to drug deals orchestrated by the cartel and the Byrdes as their accountants.
Fans of the show will remember that season four opened with a flash-forward scene of Marty, Wendy and their children Charlotte and Jonah speeding away from the Ozarks and back towards Chicago, believing they had finally escaped their life of crime.
However, their car was run off the road and flipped over in a dramatic crash, with who was responsible and who survived remaining to be seen.
The hit series follows the Byrdes as they are drawn into working as accountants for a dangerous Mexican drug gang and removed from Chicago to operate from the Ozarks, where they make their fortune and set up a philanthropic organisation - but at the expense of huge numbers of murders and the danger of the cartel turning on them.
In season four they had been working towards breaking free of their debt to Navarro by helping him gain freedom in the US, but plans went awry when Javi became involved.
Ozark seasons 1 - 3 and part one of 4 are now streaming on Netflix, with part two available from 29 April.
