Silva Ring is a world-famous singer with a severe hang-up about her age. When a Swedish interviewer produces her true birth certificate, she resorts to increasingly desperate measures to prove him wrong. With help from her long-term housekeeper, Dolores, Silva pretends to be her own sister, Iris, a tough lady who can make tough decisions. Silva's lover, a footballer, her agent, and Dolores all suffer from the iron rule of Iris. Lola Wales, an old singer, is brought in to be an aunt, and a petty forger is persuaded to attempt to destroy Silva's files at the Family Record Center. After a wild climax during which Silva scores a goal at Wembley Stadium, she can no longer juggle all her lies and subterfuges, and she escapes by having a bogus nervous breakdown. A victim of fame and wealth, she wins in the end and emerges stronger than ever.
