Iris Sellin (Potente) is a world-famous pianist and composer who finds out that she is suffering from multiple sclerosis, a degenerative nerve disorder that will gradually stop her being able to perform. She asks a friend Dr. Martin Fisher (Thomsen), a revolutionary reproductive researcher, to assist her in creating her clone so that she can pass her music onto her daughter. Even though cloning of humans is illegal, Dr. Fisher agrees so that he will forever be known as the first. The procedure is a success and Iris gives birth to Siri (Potente). Siri closely resembles her mother in both facial features and musical talent.
When Siri finds out at the age of thirteen that she is her mother’s clone, her whole world falls apart. The once very close and sweet relationship between mother and daughter turns into an emotional struggle. They fight for the same man, compete with their musical careers, and nearly pay with their lives. —Wikipedia
