The story follows three fifty-something women who set out to repeat the European inter-railing adventures of their youth after their close friend passes away and leaves them rail tickets. However, her final request is that they take her teenage daughter along with them.

After the death of their adoptive mother, a shy butcher and his drama queen twin sister leave the UK and adventure to Australia in search of their biological mother, but the local townsfolk of Two Heads Creek are hiding a dark secret: the pair must reconcile their differences to fight for their lives in this playfully dark comedy-horror.
