26. srpnja 2009., Diane Schuler vozila je krivim smjerom gotovo 3 km na Taconic Parkwayu u New Yorku, a zatim se zabila u nadolazeći terenac, ubivši sebe, svoju kćer, tri nećakinje i sve troje putnika u drugom automobilu. Samo je njezin petogodišnji sin preživio. Dianeina autopsija otkrila je da je konzumirala deset čašica votke i popušila marihuanu nedugo prije nesreće. Nagrađivana redateljica Liz Garbus istražuje činjenice i špekulacije vezane za ovu tragičnu nesreću. Je li Diane Schuler bila čudovište kakvom ju je javnost vidjela? Ili idealna supruga i majka kakvom je opisuju mnogi koji su je poznavali?
