After working on the McMasters' case, where toxic family dynamics were on full display, Lacey is ready to make amends with her estranged brothers, so she boards a bus to Chicago, with Hardley in tow, to pay them a visit.

A wicked rainstorm moves in, causing Lacey to have second thoughts about the trip. Her fellow passengers are just as much on edge as she is, but for some, it has nothing to do with the weather. Poor visibility, flooded roads, they take shelter at a mountain lodge to wait for the storm to pass. Tensions rise. Someone dies. And now Lacey's trip back home turns into a mystery to solve.
