Many of the crimes that the Star Cops investigate have a science fiction "twist" to them arising from the unconventional (for a police show) environment the series is set e.g. a murder in which the two victims are not yet dead, a ransom demand for kidnapped embryos, a hoax discovery of an alien civilisation, etc. It is out of these scenarios that one of the major themes of the series emerges: the conflict between human emotion and morality on the one hand and machine logic and rogue science on the other.
