Meanwhile Katy, a fun-loving young woman, wakes up with a severe hangover and memory-loss, along with a mysterious man in her bed. Trapped inside her apartment with this stranger and her paranoid housemate Jenny, Katy begins to suspect that she may have just slept with the wanted terrorist and is forced to find a way to escape.
