Anu Singh, an Australian National University student, drugged her boyfriend Joe Cinque's coffee with Rohypnol and injected him with heroin in 1997.

[11] Reviewing for The Guardian, Luke Buckmaster gave the film 2 stars, describing it as an adaptation of the book as "one Herculean stretch" but also "level-headed, a sobering portrait of a tragedy intentionally bereft of narrative bells and whistles.".

[13] Rochelle Siemienowicz praised elements of the film's cinematography and wrote that the mentality of the times was captured realistically, but lamented that dialogue delivered by Sacha Joseph as Madhavi Rao made the character seem robotic.

[15] Richard Kuipers, writing for Variety in North America, gave a positive review: "[the film] offers a moody and compelling study of the facts while leaving audiences to draw their own conclusions to the burning question of why people would act like this".

Antonio Gambale's fine score slides nicely from bouncy rhythms in early, happy times to brooding soundscapes as Singh’s monstrous plan takes shape.

[16] Richard Gray at The Reel Bits gave it 4½ stars and described it as "a complex love story, a plot for murder and an intense character study".
