The mysterious Emmie is arrested late one night in the ruins of an old house. Brigadier Rosa Scheffers suspects that something unusual is afoot, and uses the opportunity to re-establish a special unit: Sergeant Beatrice Mack and Colonel Bas Koorts call themselves the Spreeus. Soon, it appears that Rosa's suspicions were correct.

Emmie's jealous husband, Petrus, tries to convince the Spreeus that she is out of her mind. Bas suspects he is not telling them the full story, and a supernatural encounter confirms his suspicions. Beatrice remains skeptical and Bas's attempts to convince her almost lead to fatal consequences for Emmie.

Beatrice befriends Rasheeda, a Bo-Kaap widow who is about to be evicted by developers. When she tries to help, the Spreeus discover that Rasheeda has a visitor from the distant past - and that she will not let herself be shunted around so easily.

The Spreeus are called in to investigate a fatal accident in the Karoo. They find a broken town, struggling to deal with years of road deaths. What's more, the accident - and the mysterious hitch-hiker who caused it - threaten to destroy a young couple's relationship. Bas and Beatrice decide to take a drive themselves.

Local policeman Vonnie helps the Spreeus solve the mystery of the mysterious hitch-hiker. But to stop the deaths along the road, they need to dig up the past, and try to heal old wounds. Bas and Beatrice's plan tries to bring consolation, not only for the ghosts, but for the town itself.
