Bjorn Runge's dark drama Mouth to Mouth concerns a family that is weighed down by a history of secrets and bad behavior. Vera (Sofia Westberg) moves out of her parents' house after her father Mats (Peter Andersson) strikes her during a drunken tirade. One ear later she lives in squalor with a boyfriend who sells her body in order to feed their heroin habit. Vera's mother Eva (Marie Richardson) has slipped into a fragile emotional state since her oldest left home, and the two youngest kids are having a difficult time adjusting to their mother's condition. Mats quits drinking cold turkey, and soon comes up with a plan to make up for the damage he's caused, a plan he sets into motion by physically forcing his daughter to return home.
