After their '60s movie becomes a revival hit, three aging movie stars (Oscar winner Shirley MacLaine, Oscar nominee Debbie Reynolds and Joan Collins) are given a chance to join forces for a one-time televised concert, if they can overcome their long-standing animosity toward one another. Even when a legendary agent (Oscar winner Elizabeth Taylor) achieves the seemingly impossible task of getting the three to agree to the concert, the producers, worries aren't over. The drama has only just begun!
