Freakdog is a 2008 horror film by Paddy Breathnach, that originally went under the title 'Red Mist'.
The film circles around four medical students who, while out partying one night, spike the drink of a unknowing and loner colleague nicknamed 'Freakdog'; it turned out to be a very powerful sedative that accidentally puts him into a coma. The students, not wanting to be involved or else risk their futures for their crime, abandon his body on a road and drive off as fast as they can, hoping someone will come across his body and help him. When they learn about his condition becoming fatal, one of the students (Arielle Kebbel) attempts to revive him using an experimental drug. The result has horrible and unintended consequences which leads to the colleague having out of body experiences that seem to possess the students who poisoned him and abandoned him, which he is using as means to exact vengeance by possessing their bodies and through them, framing them for murdering each other while they desperately find a way to stop him.
A young doctor in a US hospital administers a powerful and untested cocktail of drugs to a coma victim. But instead of curing him, it triggers a powerful "out-of-body" experience and enables the patient - a depraved and dangerous loner - to inhabit other people's bodies and, through them, take revenge on the bullying medical students who were accidentally responsible for his condition. The doctor, who was herself a part of this group, is also targeted and as her colleagues are singled out and relentlessly picked off, she realises that she can trust no-one - friend or stranger - as this comatose killer moves in and out of bodies at will, getting ever closer as his murderous supernatural powers increase.
