It's raining family in Ann Arbor. Sady gets a surprise visit from a relative she didn't know existed. And Matt is entertaining his mother while dealing with the fallout from the bomb he dropped when she unexpectedly showed up on his doorstep.
Amanda takes matters into her own hands to help Matt's mom, Ellen, while Sady returns to the place her adventures started- Sinful, Louisiana. She joins her cousin on a trip to explore an unsolved mystery from the 1930s. A jealous Matt follows and gets caught up in the adventure with them.
Meanwhile, in Michigan, Amanda handles her first case with her usual sarcasm and sass- much to Harry's dismay and CJ's amusement.
