In 1999, South African emigrant psychiatrist Colin Bouwer murdered his wife in what he thought was an undetectable manner. He was not counting on the skills and tenacity of New Zealand police and his colleagues in the medical profession.

Unexpectedly thrown together after a decade apart, the show follows former romantic partners Deb Brighton and Mihi Renata, who are forced to partner up again as cops on the beat in the fictional town of Waitote, in the north of New Zealand. Each episode of Bust Up will centre on a stand-alone crime with the duo’s slow-burning relationship story unfolding across the series.
