In a city bar, a detective, lost in alcohol and in the middle of the umpteenth depressive crisis, falls into the vacuity of life. But, with the appearance of a mysterious letter under his drink, everything is going to change.
The detective can't sleep. His insomnia is due to the memory of the femme fatale met a few hours before, but his feelings are interrupted by a phone call which announces a murder.
That's the reckoning! The detective, confined to a wheelchair for the too much leg pain, is getting close to intuit everything. But there's still an obstacle to overcome: Joyce Happy.
