The outrageous antics of the three Verdeen cousins - Gaynelle, Peaches, and Jimmie Wyvette - have become the talk of the town in Sweetgum, not the least of which is Gaynelle's "accidentally" crashing her minivan through the bedroom of her husband’s girlfriend’s doublewide. But Peaches and Jimmie Wyvette have decided that their family reunion's success is the perfect way to prove Gaynelle’s sanity to a skeptical court-appointed psychologist. Things spin hilariously out of control as a neighbor's pet devours all the food, a one-eyed suitor shows up to declare his love, and a high-stakes wager is made on who bakes the best red velvet cake.
