Upon further examination of her harness, she found that the two sets of needles attached to her torso were connected to her ribcage, each needle hooking into an individual rib. Each array of needles was attached to one of two metal arches resting behind her, that, for the time being, remained folded. Hanging before her was a jar filled with acid into which a key was dropped upon her regaining consciousness. The jar was also suspended by chains, and was tightly fastened so as to be unable to tip over. A television turned on in front of her and delivered the instructions to Kerry's test.Billy informed Kerry that she was placed in the test because she was "dead on the inside," explaining why she was so adept at her job as a Forensic Detective. He also implied that the device Kerry was equipped with would tear her ribcage from her body, knowing that Kerry would understand from her experience with Jigsaw's previous tests. Billy told her that she would have one minute to retrieve the key from the jar before the key was dissolved by the acid and before the timer on the device ran out. After hesitating, Kerry plunged her hand into the jar, severely burning it, but failed to grab the key. Screaming in pain, she plunged her hand in a second time and successfully retrieved the key. She pulled out her bloodied, severely corroded hand, and unlocked the padlock on her harness.
Upon removing the lock, however, she found that she was unable to remove the harness itself. It is then that she realized that the trap was never intended to be escapable, as each of the pins were hooked directly into her ribcage, and there was a second lock at the back of the device that held it in place. As Kerry realized this, Amanda entered the room, revealing herself as the inventor of the trap. With that revelation, Kerry raised her arms and clenched the chains she was hanging from as the two arms attached to the harness swiftly arched upwards in a similar manner to a pair of wings (hence the name of the trap), and pulled each side of the harness with them, causing the needles embedded in her torso to rip both sides of her ribcage out in opposite directions. She soon collapsed and died in the leather straps as her internal organs spilled out onto the floor.
The Angel Trap was later discovered by Officer Rigg and Detective Hoffman, followed by Strahm and Perez.
Kerry's last word when Amanda enters the room.
This was the second of Amanda's inescapable traps.
Original Idea: According to producers Mark Burg and Oren Koules, they had originally discussed having Kerry placed in a device that would pull her arms and legs in four different directions, but instead decided on the ribcage trap. However the idea was used in the Saw IV Bedroom Trap.
Hello, Kerry. I want to play a game. Up until now, you have spent your life among the dead, piecing together their final moments. You're good at this because you, like them, are also dead. Dead... on the inside. You identify more with a cold corpse than you do with a living human. I believe you want to join your true family, indeed your only family, in death. The device you are wearing is hooked into your ribcage, and by the time this tape is finished, you will have one minute to find a way out. At the end of that minute... you should know better than anyone what happens then. There is a simple key that will unlock the harness, Kerry. It is right in front of you. All you have to do is reach in and take it. But do it quickly. The acid will dissolve the key in a matter of seconds... Make your choice.
Jigsaw explain the rules
- The concept was later reused for the first Saw video game. At several points the player must reach into large barrels of acid in order to retrieve key in order to progess further in the game. However the keys will not dissolve in the acid. (A real world explanation could be that the keys are made of a metal that does not react with the acid used.)
- The function of this trap is similar to the Blood eagle method of ancient Nordic execution.
