Threshold

In Threshold, Scott Dawson faces a desperate situation when his wife, Holly, goes missing, leaving their family on the brink of financial ruin. Unexpectedly, they receive aid from a deceased uncle, Alastair, whose will imposes eerie stipulations: they must live in his ancient estate, the children can never leave the grounds simultaneously, and entry to the basement is strictly forbidden. As the family navigates their new home filled with haunting secrets, they must confront whether these conditions will lead to their salvation or downfall.
