Teen Wolf star's horror movie confirms release date with trailer

The 100-second trailer opens with the ominous sight of a body bag being zipped up before we see couple Emmet (Gallner) and Anya (Roden) scattering some ashes at an idyllic lakeside spot – where they are later seen having some frank conversations with one another.

Things take a turn for the sinister when Anya starts behaving in an increasingly unusual manner, culminating in a moment in which Emmet appears to ask her: "Are you my mother?"

If that clip has left you scratching your head a little, then the official synopsis might provide a little more clarity about what to expect from the film.

It reads: "Emmett enters into a nightmarish game of therapy with his wife Anya, who has inexplicably taken on the persona of his estranged and recently-deceased mother.

"Bizarre and creepy in equal doses, this psychological thriller will keep you guessing if this is truly possession or just a twisted battle of wills."
