In the heady summer of 1977, a naive young woman called Calista sets out from Athens to venture into the wider world. On a Greek island that has been turned into a film set, she finds herself working for the famed Hollywood director Billy Wilder, about whom she knows almost nothing. But the time she spends in this glamorous, unfamiliar new life will change her for good.

While Calista is thrilled with her new adventure, Wilder himself is living with the realisation that his star may be on the wane.
