Heaven Knows What blends fiction, formalism and raw documentary as it follows a young heroin addict (Arielle Holmes, in her searing film debut) who finds mad love in the streets of New York. Harley (Holmes) loves Ilya (Caleb Landry Jones). He gives her life purpose, sets her passion ablaze. So when he asks her to prove her love by slitting her wrists, she obliges with only mild hesitation, perhaps because of her other all-consuming love: heroin. Heaven Knows What, by celebrated filmmaker brothers Josh and Benny Safdie, is based on Holmes' memoir Mad Love in New York City. Also starring street legend Buddy Duress and gore rap phenom Necro.
