Acid Room Public Execution Trap Pain Train

Are you both strong enough to walk away from what is destroying you or will you fight one more time for the heart that binds?
— Hoffman's ultimatum for Brad and Ryan[src]

The Public Execution Trap is a trap from the Saw franchise, appearing in Saw 3D.

Design and Function

This trap was located inside the Welthammer Store, a home improvement market located in a public square. It consisted of a mechanical contraption positioned in the center of the room. Attached to both sides of it were circular saw blades. In the middle of the contraption was a movable device with another blade. Two test subjects were chained to either side of the contraption, while a third one was chained to a large metal plate suspended from the ceiling above the third blade. Once the game began, the first two victims had 60 seconds to kill each other by pushing the saws all the way to the other side. Only if one of them achieved this goal and thereby killed their opponent, the third victim could be saved. Otherwise, the plate would be lowered down once the timer went off, causing the third person to be horizontally sliced in half by the saw blade underneath. (Saw 3D)


Brad and Ryan's Test

Hello, Brad. Hello, Ryan. I want to play a game. The same woman has played each of you for a fool, manipulating your love for her and causing nothing but pain. Her fun and games pushed you both to break the law to fulfill her material needs. She is toxic. And today, all of your transgressions will be made public. Now you must choose who will drop out of this triangle, for within sixty seconds, one of you must die. If you wish to save her, then the saws must be pushed all the way to one side or the other, sparing her while proving who is indeed the alpha male. Are you both strong enough to walk away from what is destroying you or will you fight one more time for the heart that binds? You have sixty seconds to decide. Live or die. Make your choice.
— Brad and Ryan's tape[src]

The people tested in this trap were Brad, Ryan and Dina. Dina had cheated on both of them and had caused them to commit various crimes in order to fulfill her own material needs. One day, all of them were abducted and taken to the Welthammer Store.

Ryan sees Dina

Brad was the first one who woke up shortly afterwards and was shocked to see that his hands were chained to a contraption, consisting of three circular saw blades, in the middle of the store. To his surprise, Ryan was chained to the same contraption. As they started to panic, Ryan yelled at the crowd outside the shop window and begged them to help them. Seconds later, a black cloth was pulled away from the large metal plate suspended from the ceiling above them, revealing Dina, who was chained to the plate and immediately screamed for help. Brad then yelled at the people outside to call the police. As he saw that a woman in the crowd had a briefcase, he frantically told her to use it to smash the glass. However, despite her repeated attempts she was unable to break the window. Seconds later, a mechanical ventriloquist puppet approached on a tricycle and introduced them to a deadly game. The puppet told them that they were chosen because of their crimes they committed in Dina's name and informed them, that one of them had to die within the next 60 seconds. In order to save Dina, either Brad or Ryan had to push the saws before them all the way to the other side, thereby inevitably killing one of them. If none of them managed to do this in time, Dina would be killed by the third saw blade.

Dina is killed by the blade

Moments later, the timer began to count down and the blades started rotating. Therefore, Ryan immediately pushed the saws away towards the shocked Brad. Brad however fought back and shoved the saws towards Ryan. As he seemingly gained the upper hand, Dina told him that she loved him, which he reciprocated, and encouraged him to kill Ryan, much to the latter's dismay. However, when he tried to deal the death blow to Ryan, he fought back once more, causing one of the saws to vertically slice Brad's chest while he screamed in agony. Afterwards, Ryan confronted Dina, who claimed that she only loved him and had merely told Brad that she loved him as it was the only way for her to save herself. Ryan however was furious and when Dina yelled at him to kill Brad, he pulled the saws away from him. Seeing that Dina had played with both of them, Ryan told Brad that she wasn't worth either of their lives and thereby convinced him to sacrifice Dina in order to save themselves. Dina, who was shocked by this, angrily yelled at them. Moments later, the timer went off and Dina was lowered down, causing the third saw to slowly cut her stomach. Thereby, Brad and Ryan were covered in her blood until the saws finally came to a standstill after slicing Dina's body. (Saw 3D)


The police finally arrived immediately afterwards and freed both, Brad and Ryan, from their shackles. Dina's corpse was then taken to the police station, where she was obduced by Dr. Adam Heffner, while the contraption with the blades as well as the plate to which she had been chained were taken to the evidence room. (Saw VI, 3D)


  • Originally, Dr. Lawrence Gordon was supposed to be in the crowd along with John Kramer as they watched the game.
  • In an earlier version of the script, Brad was written to kill Ryan and thereby save Dina from the trap.
  • Dina's death is similar to the original concept of the Pig Vat, in which the victim, Judge Halden, was supposed to be lowered down into a blender.
  • In November 2010, Saw 3D was accidentally screened by a branch of Showcase Cinemas for a group of seven-year old children celebrating a birthday who had come to watch the DreamWorks Animation film Megamind. It took several minutes for the cinemas employees to rectify the mistake, requesting the children to cover their eyes, but it took long enough for the children to see the Public Execution Trap scene.
