Albert’s beloved sister, Anna, is abducted from their family home by shadows. He sets out to find her and meets Otto, her stuffed bunny, along the way.

When Albert picks up Otto, he gains special powers, and the two work together to overcome murderous beasts and lethal puzzles.

Anna appears to Albert in recurring sequences, suggesting that the journey to save her is not what it seems. Clues during gameplay also indicate that Albert may be hiding something from the player and himself.
