The story begins in 1997. It’s the dead of night in the city of Los Angeles,
and there has been a mass murder at a general hospital on the outskirts of
downtown. The perpetrator is the director of the hospital, Richter Harris. He
has shut himself up in the hospital and taken a number of patients as
hostages, leaving the police helpless and unable to move in. Richter’s only
daughter, Laura Harris, after hearing the situation, rushes to Los Angeles
from San Francisco, and drives alone to the tragic scene at the hospital
ground. Upon entering the hospital Laura finds herself transported to an old
mansion, while the disembodied voice of her father pleads with her to leave.
Nevertheless she must press forward to save her father and herself.

D is a puzzle game requiring Laura to solve esoteric inventory puzzles on a
very strict time limit. Each of the game’s four discs must be completed in
about thirty minutes each, and saving is not an option. The time is kept track
of using Laura’s pocket watch. The pocket watch can also be used to supply
hints for puzzles, but after three uses the glass will shatter and it will
stop working. The game also has multiple endings.
