When a young woman vanishes from a roadside motel, Mary-Alice and the gang leave Sinful and head across the border to find her. They soon find that the unprepossessing McCully Inn holds some Texas-sized secrets, which the influential McCully family would prefer to keep hidden.

But with the missing woman's life at stake, the ladies decide to keep poking around the McCully family closet and let the skeletons fall where they may. And with their technical know-how, decades of experience, and relaxed attitude about rules and procedures, they might just get to the truth.
