When a tree topples over onto Miss Lillian’s prized 1948 Tucker Torpedo, the grannies are once again scrambling for money and keeping Lil in the dark. Lucky for them, they have their choice of two cases, but which to take—a suspected art forgery or mysteriously disappearing trash from the county landfill? As usual, things aren’t exactly as they first seem, and the grannies soon find themselves going undercover and dumpster diving to track down both bad guys. And now that Lil has scored an unexpected early release from prison, the grannies have more at stake than ever. Will they find the culprits in time to repair the Tucker before Lil gets home, or will she arrive and unravel their lies?
