This jaw-dropping true crime video documentary by Dan Klores and Fisher Stevens neatly balances tabloid headlines and unfathomable intimacy. Burt Pugach and Linda Riss met in the Bronx in the late 50s, when he was a high-rolling ambulance chaser and she a stunning 20-year-old; their love affair soured when he welshed on his promise to divorce his wife, and from there the story descends into a thicket of lies, cruelty, and passion run amok. Klores and Stevens don’t have much to work with visually besides talking heads, old photos, news clippings, and stock footage, but with a narrative this insane, that’s more than enough. PG-13, 92 min.
