FilmRise has unveiled an official trailer for Broken Diamonds, the latest from filmmaker Peter Sattler, revolving around a young writer unwillingly take in his unpredictable sister after family tragedy.

The film just premiered at this year's Santa Barbara Film Festival a few months ago. The film stars Ben Platt, Lola Kirke, Yvette Nicole Brown, Alphonso McAuley, Lynda Boyd, and Peter Benson.

In the wake of his father's death, a 20-something writer sees his dream of moving to Paris put in jeopardy when he's forced to temporarily take in his wildly unpredictable, mentally ill sister. The screenplay is written by Steve Waverly and produced by Molly Smith, Thad Luckinbill, Trent Luckinbill, Rachel Smith, and Trina Wyatt.

The film releases on 23rd July.
