Karma has landed on , so how does the Korean crime thriller end?

Dropping in its entirety on April 4, the thrilling Karma, inspired by Choi Hee-sun's webcomic, plunges into a chilling maze of crimes.

The series weaves a tale where each sinister chain of events pushes characters towards their inevitable ruin.

Trouble erupts when Park Jae-yeong (interpreted by Lee Hee-jun), under pressure from brutal loan sharks, plots his own father's demise for the life insurance money.

Involving his former colleague Gil-ryong (portrayed by Kim Sung-kyun) proves disastrous as he invites the volatile ex-cellmate Kim Beom-jun (Park Hae-soo of 'Squid Game') along and chaos ensues.

Netflix's Karma reaches its climactic close with the final episode unleashing tragedy at an isolated warehouse.

Karma on Netflix ending explained

Here, Kim has already killed Gil-ryong and is on the brink of setting Park ablaze, bound and helpless.

Park didn't realise though that his soon-to-be killer went to the same school as him, graduating three years prior.

This disastrous reunion, however, becomes Kim's twisted windfall as he's now fleeing after fatally wielding a shovel against GP Han Sang-hun (played by Lee Kwang-soo).

In a cruel con, Kim and cohort Lee Yu-jeong (Gong Seung-yeon) duped Han into believing he was responsible for Park's dad's death, which had actually occurred earlier.

Han was killed by Lee, who had been masquerading as his girlfriend, only for Kim to exact revenge by murdering him.

Unfortunately for Kim, Han's wife had hired private detectives to follow her husband, resulting in the murder being captured on camera, leaving Kim now desperately evading the police.

Kim's twisted scheme involved killing Park to assume his identity and claim the life insurance payout.

However, as Park was engulfed in flames, a piece of the warehouse ceiling collapsed, trapping and severely burning Kim, ironically aiding his disguise as Park with his fingerprints also destroyed, rendering his DNA untraceable.

Assuming Park's identity, Kim is hospitalised and treated by Dr Joo-yeon (Shin Min-a), who is horrified upon hearing Park's name, as he was part of a group that sexually assaulted her during their school years in a cruel "prank" orchestrated by her envious classmate Lee, Kim's co-conspirator.

Once discharged, Kim focuses on securing the life insurance funds from Park's late father.

But in a bitter turn, he discovers that Park's father had changed his will, bequeathing the fortune to the church instead of his son, which sends Kim into a fury.

Before his confrontation with a nun at the church, Joo-yeon procures medication from the hospital and employs her private detective to swap Kim's tablets with these drugs.

As Kim departs from the church and enters the alley where Park's father was murdered, he becomes lethargic and collapses, immobilised.

Joo-yeon is present, anticipating his defencelessness so she can cut his throat. However, her doctor friend intervenes, persuading her that she would regret committing murder.

Ultimately, she concedes that he is correct and leaves Kim lying on the ground.

While Kim narrowly avoids death, the police are closing in as they identify inconsistencies in his accounts of the warehouse fire and realise he isn't Park.

Kim contemplates fleeing when an alarm on Park's phone rings, indicating that time has run out to repay the loan sharks - a predicament Kim is unaware of.

At this juncture, a tinted car arrives, and goons emerge, hauling Kim into the back.

They transport him to the location where Park was initially taken, tied to a table where a doctor was dissecting a body, in an attempt to intimidate Park into repaying the loan sharks.

Of course, it is actually Kim they have seized, but no one believes him when he insists he isn't Park.

Another unexpected revelation comes at the finale's conclusion when it is unveiled that the doctor dissecting the body at the start was the friend and colleague of Joo-yeon.

He had begun collaborating with loan sharks, killing and intimidating those who fail to repay their debts, as a means to fund his medical education.

So, when he recognises Kim, believed to be Park, on the operating table, he relishes in murdering him without general anaesthesia to ensure his death is as agonising as possible.

The doctor refrains from telling Joo-yeon about Park's fate, but she appears to have released her resentment.

She confesses to sleeping better, comforted by the knowledge that she took the moral high ground and refrained from seeking revenge.

Karma is available to watch on Netflix.
