On the eve of their one-year wedding anniversary, Jules and Jackie become embroiled in a merciless fight for their lives when they find themselves pitted against the most unexpected of adversaries: each other. As violence rains down upon their idyllic forest getaway, the women engage in a frenzied psychological and vicious battle that will test the very limits of their instinct to survive. From the mind of Colin Minihan, director of GRAVE ENCOUNTERS and IT STAINS THE SANDS RED, WHAT KEEPS YOU ALIVE is a knife to the throat of 21st century genre cinema.
