Drill sound for about a full minute at the top of the fourth story and then sounds of pulling whatever was drilled out of the hole and pushing something else in
There's a scene w a character stuck in traffic and his windows are open. You distinctly hear a baby cry but it's ambiguous where the cries come from and you don't see a baby.
Someone is hung but escapes. Someone is choked briefly but people remove the person's hands who was choking her. A bunch of people cry and sob and choke through tears.
Many of theses vignettes could be described as people torturing each other, not always physically. But there isn't a single torture scene of physical brutality.
It's implied that the person flying (and crashing) the plane in the first story is mentally ill. All the vignettes are people pushed past their limits who become violent and arguably they are all or mostly experiencing psychotic breaks.
The plane film has an implied murder-suicide plane crash and the wedding film has a reference to suicide (the bride contemplates jumping off a building and later mentions jumping off a bridge).
Many of the vignettes end sadly or on a melancholy note but the movie as a whole ends on an up note with a couple getting back together. Also the general tone of the film is darkly comic, not sad.
One car pushes another car down an embankment into water and it flips upside down. Later a car looses its tire and goes down the same embankment, landing vertically, balanced on the other car. Both cars explode in a ball of fire.
Someone is stabbed and someone else gets up from the floor, where they'd been lying in a giant pool of blood.
Later we see two men bloodied from fighting, especially on their faces, and then their skulls after they die in a fire.
I'm the wedding scene, the bride gets bits of blood, her own and other people's, on her. She throws another woman into a mirror, which shatters, and we see that woman covered in cuts and blood.
And later, in the next story, a huge structure is professionally demolished using explosives. We see the building collapse and balls of dust and smoke. And then in that story a car explodes as well.
