A retired Louisiana cop and his wife hit the road in their RV but must pull over to investigate a serial killer in this mystery series debut.

Recently retired homicide detective Hank Moran and his wife Helen have just purchased a new motorhome and are ready to take a two-month tour to see the country. The discovery of a series of murders on their short trial run to Biloxi, Mississippi, puts their tour on hold while Hank investigates.

The prime suspect is a firebrand tent revival preacher who literally takes God's word for the Old Testament punishment of evildoers.

Their adventure takes them, of all places, into a gay men's RV resort for the explosive finale.
