Jennifer Shannon has made a career of finding rare garage sale treasures to resell at the consignment store she owns with her business partner, Dani. When she finds a wedding dress that was worn on the day a groom went missing, Jennifer uses her knack for solving puzzles to investigate this unsolved cold case. After meeting the dress’s original owner, Helen, and finding traces of blood on the dress, Jennifer digs deeper into the decades-old mystery with the help of Detective Lynwood, and the support of her husband, Jason. With every clue that Jennifer uncovers, she gets closer to either finding the long-missing groom, or uncovering a wedding day murder.
Unfortunately the movie Garage Sale Mystery: The Wedding Dress is not yet available on HBO Max.
