Sze Sai Lun, along with his family, comes into town to be its new judge. He soon ends up having to sentence the town fool. When the fool ends up hanged at his house, Wong Tin Pak is blamed for his suicide by all the town's people. Everything seems like it is getting worse and worse until Sai Lun finds a simple ceramic pillow by accident. The pillow contains a helpful (but not too helpful) spirit who tries to help him solve the case.
- Note: Mysteries tend to cross over in several episodes, especially the endings of one and the start of the next.
Mystery 1 Steamed buns of death - When a recently sentenced man is found dead, the judge is blamed for causing his suicide, but was it really a suicide? or is their something a little more sinister going on?
Mystery 2 The Man and the Monk - When the famed thief, The Golden Fox, shows up, a murder case from the past comes back to haunt the men involved. Taels of gold, red paint, ants, and some funky soup all contribute to the mystery.
Mystery 3 The Golden Fox is back... - and a family heirloom is missing. Will the head guard get his chance to finally catch the foe that has eluded him so long? And a lover from the past comes back to throw doubt on what was previously assumed.
Mystery 4 Runaway Bride - Sze Sai Lun is about to marry his fourth wife, Heung, on the 3rd day of the 3rd month, when she disappears from her wedding chair. What happened to her and why is the Pillow Spirit walking around?
Mystery 5 The Fugitive - Tin Pak has run off with Ming, and the Prince is not happy about this. Things go from bad to worse when Tin Pak is accused of killing Commander Pong. And why has the Pillow Spirit been acting even weirder than normal?
Mystery 6 Dr. Feel-Good - Tin Pak has been proven innocent, but what deadly reason would Ming need four doctors for? The reason is as simple as black and white.
