Till Death ending spoilers follow.

While Till Death is not a Netflix original movie, it's absolutely the type of high-concept thriller that could go big on the streaming service now it's arrived on Netflix UK.

Unhappy in her marriage to Mark (Eoin Macken) and having an affair with his employee Tom (Aml Ameen), Emma (Megan Fox) is surprised by her husband with a trip to their secluded lake house to celebrate their 11th anniversary.

He wants them to give their marriage a second chance and they share a romantic evening together. However, she wakes up the next morning to find herself handcuffed to Mark just before he kills himself. It's the dead of winter with no help in site, so how the hell will Emma manage to survive?

We're about to go into all of the wild twists in Till Death right up to its ending, so major spoilers await if you haven't seen the movie yet.

Till Death ending explained

After Mark kills himself, Emma tries all the logical things to get her out of the pickle she's found herself in. She tries the phone but can't get any reception, and then she tries to use Mark's gun to shoot the handcuffs, but it's out of bullets. (Later when she goes to the basement, she finds all of the tools are missing.)

Mark has thought of everything, it seems, as after she drags him downstairs, Emma finds her phone submerged in the vase. When she makes it to the car, she discovers it's been drained of petrol and Mark has recorded a posthumous message for her which plays out on the car stereo.

It's mostly just him taunting her for being "nothing" when he met her and that she should be grateful for him, revealing that he knew she was having an affair with Tom. He didn't kill himself because of it, but says he was "being called away and I couldn't sit back and watch you live happily ever after with him".

It's not made clear why Mark was being "called away" until Tom surprisingly shows up at the house, having received a message from Emma (which was really sent by Mark) that she needed his help. It turns out that the DA has raided Mark's office and he's being charged with several counts of tampering with evidence.

Before Tom can help Emma "manage the truth" of the wild situation she's found herself in, Jimmy (Jack Roth) shows up and claims to be there to fix a burst pipe. Tom pays him to go away, but he sticks around and soon his brother Bobby (Callan Mulvey) arrives and kills Tom.

Bobby is revealed to be the person who attacked Emma a decade earlier, leading to Mark successfully getting him convicted. It's how Mark met Emma, but since their relationship soured over the years, Mark ended up helping Bobby leave prison after 10 years by tampering with evidence.

Mark hired them to rob the lake house and promised that the safe had $200,000 worth of diamonds, seen by Bobby as recompense for his time in prison. So begins a bit of a cat-and-mouse game between Emma and the two intruders, but she does at least manage to free herself of Mark's corpse by cutting his thumb off with a boat anchor.

Despite her best efforts, Emma is eventually captured by Bobby and as she tries to get through to the police, he knocks her out. She wakes up handcuffed to Mark's corpse again (bit harsh), and Bobby needs her to tell him the combination to the safe which Mark had told Bobby was the date that Mark proposed to Emma.

She refuses and Bobby threatens to cut off her toes to force her to give him the combination, before Jimmy pulls a gun on his brother as he doesn't want anybody else getting hurt.

Jimmy makes a deal with Emma where in exchange for the combination, he'll free her from the handcuffs. Bobby opens the safe, but all he finds in there is a bonesaw with a message on: "The diamonds you seek lay close to her heart."

It turns out that the diamonds they want are in the steel necklace that Mark gifted Emma at their anniversary dinner (because 11 years is steel). Emma had already tried to remove the necklace, but found it locked on and the bonesaw won't exactly help. "He doesn't want us to cut the necklace off her. He wants us to cut her off the necklace," Bobby says.

Jimmy tries to stop Bobby cutting Emma's head off and as Bobby fights him off, he accidentally impales Jimmy on a coat hook, killing him. Needless to say, he's annoyed and blames Emma, but she manages to fight back and handcuffs Bobby to Mark's corpse.

Dragging Mark's body with him, Bobby chases Emma outside onto the ice and during their fight, the ice cracks and they fall into the ice. As they struggle in the ice-cold water, Emma stabs Bobby in the eye with the knife she took from the house and he's pulled down into the abyss by the weight of Mark's body.

Emma manages to use the knife to break the surface and crawls onto the surface. She takes off her wedding ring and throws it away, unsurprisingly, and as she catches her breath, we hear police sirens coming as a result of her failed call earlier.

Phew.

Till Death is available to watch on Netflix in the UK.
