Bound Together

One night, siblings Elias and Nora wake up in their dark house and follow a strange column of light to an old castle. Elias falls through a hidden trapdoor into a prison cell, while Nora is locked inside the archive behind a closing gate. Separated by stone walls and connected only by their voices and a pair of walkie-talkies, they must share what each of them can see to escape the dungeon, a forge, a series of strange laboratories, an abandoned office backup system and a deep stone quarry, slowly discovering what is really behind the place that trapped them.
