But weeks of careful planning unravel abruptly when, on their very first day operating a food truck, a body is discovered lying by their propane tanks. Suspicion immediately falls on Daisy, and Shannon is determined not to let her little sister go to jail.

And it turns out that Daisy may have had more motives for the murder than she's admitting...
