Beautiful, seductive and extremely dangerous, Franca Tantardini is one of Italy's most ruthless political extremists. When she is captured in a shoot-out, her fanatical young lover, Giancarlo Battestini, vows to set her free and, with quiet watchfulness, waits for the moment to strike. In Rome, a British businessman, Geoffery Harrison, has been taken hostage by a ruthless organised crime syndicate - kidnap is, after all, a growth industry. The British Government are adamant that they will not pay the two-million-dollar ransom and discharge responsibility to the Italian police. As political wrangling takes hold, Battestini sees a weakness and realises that the only way to secure the release of his beloved Franca is to capture Harrison and bargain his life for hers. The authorities are confronted with a terrible choice. Should they release a woman who has masterminded the murder of so many or let an innocent man die?
