Liz Garbus is on a roll. HBO premiered one of her best documentaries—Bobby Fischer Against the World—last month. And on Monday, the cable channel’s featuring her new, feature-length investigation of the 2009 Taconic Parkway disaster, There’s Something Wrong with Aunt Diane (July 25 at 9 p.m.).

The new film looks at the hours and minutes leading up to one hellish car accident—a crash that involved an SUV and a group of children, left eight people dead, and raised a host of impossible questions. Was Diane Schuler a total screw-up who got too drunk and high early one morning to notice that she was driving her two kids and three of her nieces the wrong way down the highway? If so, why didn’t any of the people she’d run into that day notice how incapacitated she must have been? And if not, how do we account for the toxicology report? Garbus interviewed friends, family members, and eyewitnesses in her attempt to find out, and absent a big reveal (in a case that will never give up its mysteries), the results are wrenching and riveting.
