A turbo-charged mash-up of sci-fi and horror, Brainjacked is the story of Tristan Davis, a young runaway who is lured to "The Garden", a rehab center for homeless youth. The Garden is overseen by the seemingly sympathetic Dr. Karas, who cures Tristan from raging migraines. Little does Tristan suspect, however, that The Garden is a front for sadistic experiments executed by Karas and his runaway minions. It's up for Tristan to stop the doctor's ultimate plans of taking over the city's youth population and making them an unbeatable street army all controlled by the evil Karas.
