Untraceable is a 2008 thriller movie.
Jennifer Marsh (Diane Lane) is a single mother and an agent for the FBI's cyber crime unit with her partner Griffin Dowd (Colin Hanks). Their new case is tracking down and trying to bring down a new Web site, KillWithMe.com, which consists of streaming video of a cat put in a Saw-esque death trap, a chatroom for comments and a viewing counter which, as it rises, makes the death trap more and more dangerous for the victim inside. As the webmaster, Owen Reilly (Joseph Cross), moves up to human victims, the site's popularity grows, making the deaths on screen happen faster and faster.
- Beauty Is Never Tarnished: Every male victim suffers through a slow and agonising death that even if someone managed to rescue them in time would leave lasting and obvious scarring. Jennifer is put in a death trap that will either kill her instantly or allow her to escape untouched.
- Bookends: the movie starts with a car ride through Portland while it rains and the radio switches from the national to the local news. The same happens in the scene before the showdown.
- Cruel and Unusual Death: Pretty much every death in the movie could count as this, but special mention goes to Griffin who is dissolved in battery acid.
- Even Evil Has Standards: For what the killer does, he would not touch Annie, and states that on the website.
- Everyone Knows Morse: Averted: Jennifer notices that a character's blinks look like morse code, but has to find somebody else to actually decipher it.
- Forced to Watch: With the whole Internet joining in.
- Humans Are Bastards: Every click brings somebody closer to death and the people keep hitting the site.
- Real Is Brown: A lot of blues and greys, very few vibrant colors.
- Revenge: The main Motivation of the Killer.
- Shout-Out: The weedwhacker is from Braindead.
- Stalker Without a Crush: the killer starting about halfway through the movie.
- Streisand Effect: In-Universe. After initially discovering KillWithMe.com, the police department issues a public service announcement warning people to stay away from it. As Jennifer predicted and feared, this only serves to increase the website's popularity.
- Truth in Television: Sadly people like some of the posters online in the movie praising the killer actually exist in real life. A recent example is a Facebook fanpage for the 'alleged' shooter of the Aurora Colorado theater shooting sprung up only to quickly disappear. A similar page was also put up for cop killer Jamie Hood. And these are just the recent examples.
- Too Dumb to Live: A couple of examples in this film. Most present one is how Jennifer gets captured. Basically, her electrically run SUV stops, she gets out of the car and walks away. Then when the SUV magically starts again, sits right back down into the driver's seat without a second thought.
- Western Terrorist: what the head of the field agent first makes him out to be. Including comparison to the Unabomber and Timothy McVeigh
- You Bastard!: The film's message is pretty much a Take That! against society's obsession over violence and Torture Porn, lampshading the message repeatedly.
