"From her childhood, watching The Sonny and Cher Show, Robyn Fisher blossomed into a superfan, with a sprawling collection of memorabilia that covers the diva’s entire career. Joining Robyn is her daughter Marina, who’s grown up alongside the collection, and show-business appraiser Marcia Tysseling, who once handled consignment items for Cher herself (and in fact sold Robyn many items in her collection). Marcia now sets a total value on everything Robyn’s collected – including such treasures as the iconic mermaid tail from Mermaids and a pair of dazzling concert-worn earrings by legendary designer Bob Mackie. Marcia then tries to tempt Robyn into a three-for-one trade for a Sonny and Cher Show rarity that makes her long to sing, “I’ve Got You, Babe.”"
