Wedding bells are in the air for Matt and Paige. You would think Ryli and Aunt Shirley would be hard at work preparing for the bachelorette party and wedding down at the family lake house. Instead, they are up to their ears in murder, mayhem, and dead bodies. Unfortunately, Ryli seems to be the number one suspect according to the Cavern Beach Police Department. Hoping to stay out of jail and make it to the wedding on time, Ryli and Aunt Shirley hunker down to catch the killer. Between jello shots and unwilling strippers, Ryli and Aunt Shirley chase down and narrow down their list of suspects. But will they find the real killer before the wedding ceremony and before Ryli is taken into custody for the murders...or more importantly, before Ryli or Aunt Shirley ends up being the next victim?
