When fractious ranger, Monzo is found dead, fallen into a dry ravine, surrounded by three Bushmen, the local police arrest the nomads. Detective 'Kubu' Bengu is on the case, which reunites him with his old school friend Khumanego, a Bushman and now an advocate for his people. Khumanego believes the arrests are motivated by racist antagonism from the police, as the Bushmen are claiming that they were at the murder scene because they were trying to help. Soon after Monzo's death, Detective 'Kubu' learns of another case involving two botany students on their way back from a specimen-collecting trip but who were later found dead, could the deaths be connected?
