A thrilling and chilling adventure through time, memory, and the mind itself—where the greatest danger isn’t just what lurks in the shadows, but what’s being erased from reality forever.

The TARDIS answers a distress signal, leading the Doctor and Martha Jones to a place that should not exist—an endless labyrinth of corridors, each holding the most precious memories of those who enter. But something is terribly wrong. The memories are being stolen, erased, and forgotten.
As the Doctor investigates, he uncovers a sinister force lurking within the Hall of Memories—a creature of shadow, hunger, and time. It feeds on the past, devouring lives piece by piece. When Martha forgets who she is, the Doctor realises the trap had actually been set for him.
Now, as Martha’s memories slip away and an ancient terror closes in, the Doctor must uncover the truth hidden at the heart of the Hall.
Who is the Keeper? And what monstrous secret lies in the core of this twisted dimension?
