A sexual assault on the owner of a pastry shop is identical to unsolved rapes that occurred at the Pyramid Chocolate factory 10 years prior. Both victims were blonde and both said the attacker smelt of sweat. The team also uncovers a series of seemingly unrelated disasters that occurred at the factory at the same time: the suicide of a female worker, the discovery of a severed finger in a chocolate bar, and the prosecution of a staff member for hiring illegal immigrants. As a connection emerges between the three events, it seems likely that a murder also took place in the factory and the rapist is still at large.
A motley crew of retired police officers re-opens troublesome cases that were never laid to rest.
