Netflix’s Lover, Stalker, Killer is a true crime documentary about a love triangle that ends in disaster. Directed by Sam Hobkinson, the documentary follows the story of Dave Kroupa, who tries to get back into the dating world by using dating apps.

The newly-single mechanic soon starts dating two women simultaneously — Shanna Golyar and Cari Farver — but the parallel relationships soon become problematic. Despite Kroupa reportedly telling Golyar that he wasn’t looking for a serious relationship, Golyar suggests the pair move in together. When Kroupa declines her offer, Golyar leaves him and begins threatening and harassing him and those close to him. The progression of the story raises questions on how far Golyar went to Kroupa — and what became of Farver.
