Supernatural horror co-written and directed by Julien Maury and Alexandre Bustillo. Engaged New Yorkers Ben (James Jagger) and Tina (Camille Rowe) are travelling across Europe together, seeking out haunted houses and recording their experiences for YouTube. When their next location in France is too crowded, a local man offers to show them to a house submerged in an artificial lake. Ben and Tina dive to the house and find it perfectly preserved, but then they begin to hear strange noises and realise they are not alone. With limited oxygen and time running out, can they escape the house before it's too late?
