Terri, Angie, Brianna, and Terri's mother, Emily, are in Door County, Wisconsin for a long-awaited vacation and the wedding of Terri's beloved cousin, Courtney Robertson. Their two weeks of rest and relaxation have barely started however when, while visiting the Cana Island Lighthouse, Terri hears and sees, a violent argument between two men. One of the men looks frighteningly familier and the other quickly turns out to be right under Terri's nose. Despite Angie's determination, 'not to get involved', they are both forced to investigate, or face a situation that could ruin the upcoming wedding and tear the Robertson family apart. Terri has also commited herself to plan and prepare, an elaborate rehearsal dinner for twelve guests. The champagne flows and all goes well but in the back of her mind, Terri is forming a plan to find out just exactly what's going on in beautiful Door County and hope their vacation and the wedding can go off without a hitch and without a body count!
