These gals are like Dirty Harry...only over 50, female, and from the south. Lillian Summer Fairview is settling right nice into the federal pen. She's even making peace with Big Martha, the toughest broad on the cellblock. After hearing Lil's granny friends recently took down a swindler, Big Martha asks Lil for a favor. Her niece has fallen for a guy she met online, and Martha's convinced Mr. Too-Good-To-Be-True is up to no good. All Lil's friends have to do is a little look-see on the guy and report back. But when they poke around, they find the guy doesn't really exist, and that triggers a wild ride through the world of online dating. Meanwhile, a cantankerous septic system on Lil's family estate in Summer Shoals, GA has the grannies fit to be tied. If Summer Haven isn't in shipshape before the historic society's inspection, they'll be in deep you-know-what. Big Martha sweetens the deal by promising to fix what ails Summer Haven if the grannies can find the elusive Romeo. Will the grannies track him down before the inspection, or will they find themselves in trouble right up to their granny panties?
