Allie (Tammin Sursok) is a young American staying in a hostel apartment building while travelling through Thailand. A friendly boarder introduces her to Cam2Cam, a popular online chat program that allows people to interact with one another. Curious, Allie logs on and soon discovers that there was a serial killer that used Cam2Cam to find his female victims, one of whom was staying in Allie's current room. After fellow boarder Marit (Sarah Bonrepaux) is murdered, Allie begins to worry that she is next on the serial killer's list.
