The documentary is centred on the group and their creation, rise to fame, exit of member Geri Halliwell, break-up and reunion. The film features narrative insight and commentary from the five girls themselves. The title of the documentary comes from chorus lyrics from their UK #1 single "Say You'll Be There".
