A person is pushed into a pipe, causing a large bloody gash on the person's face and neck; a few times we see the body lying on the ground (with an extremely bloody face and neck) and we eventually see the person choke a bit before dying. A person is impaled through the chest, causing a bloody and fatal wound; another person is stabbed with a pole, which is then pulled out of the bloody wound (another person feels around inside the bloody wound and then tapes it up). A person is shot in the heart with a tranquilizer, then the person's neck is twisted with a loud snapping sound. A person is pushed into a pool, choked, and held underwater (we see the lifeless corpse floating in the pool afterwards). A person falls down a fiery elevator chute and presumably dies. A person is torched repeatedly; the person screams and we see burnt skin falling off the body. We see a person holding a rope, and it's implied the rope is used to strangle another person to death (we later see the body fall out of a locker). A dog is thrown against the side of a cage (we briefly see some splattering through heat-sensitive goggles). A mouse is picked up by something invisible and crushed (its bloody organs and bones are visible); the scene turns out to be a computer program. A person is electrocuted after hitting a fuse box with a tire iron. We see a red serum flow through an invisible animal's veins, then watch the veins, muscles, bones, organs and skin slowly become visible again (the animal makes loud noises and thrashes); at one point during the process, the animal starts having a heart attack and is shocked with defibrillators a few times and is then fine. After a person injects a serum into an I.V. tube, the person starts convulsing violently, yelling, and eventually disappearing (during the process, we see the person's muscles, organs and bones). In another scene, we see a red serum flow through the person's veins, then see the person convulse while bones, organs and muscles reappear and then disappear. A person is bitten by an invisible animal (we hear him yell and see blood on his hand). An invisible animal is shot with a tranquilizer; also, a person tries to shoot another with a tranquilizer. A person is thrown face-first into a pole, causing a bloody facial cut; a person is punched, kicked in the face, and then knocked to the ground; a person punches another and knocks the person into a table; a person kicks another; two people are slapped; a person steps on another's neck; a person throws another around a bit and grabs the person's neck; a person is hit with a tire iron and another is nearly hit with a tire iron; a person grabs another's leg as they're climbing up a ladder, causing them both to fall and land on top of an elevator. An elevator nearly crashes into a couple of people (it does hit one person's shoulder, causing a bloody wound). A woman screams as she appears to be grabbed; the scene ends immediately afterwards, but it's implied that she's raped. A person pours several bags of blood on a floor (we see the bloody floor a few times); also, several people have bloody hands, faces and clothing, and we see several bloody corpses as well. A person with visible bones and muscles is seen a few times. Someone throws a test tube of chemicals, causing an explosion; another very large, loud explosion causes windows to break and many rooms to be consumed by fire (the flames nearly engulf a couple of people). A person vomits invisible matter into a toilet.
