The far reaching tentacles of terrorism, are felt by drug dealers, arms dealers, diamond smugglers and anyone else that resides in the murky world of organised crime. Fuelled by the promise of training and support from the Arab PLO, a militant band of freedom fighters are beginning to get a foothold in Sierra Leone. To really make a difference, they need to secure a supply of weapons but they don't have the cash. When two British arms dealers become embroiled in the lethal 'revolving door' of illicit goods, MI5 and Mossad join forces to unravel the web. The surveillance trail leads them to the Costa del Crime, where MI5's Jacob Lewis has one of his most reliable men. Having not long returned from his previous adventures, SBS veteran, John Savage soon finds himself back in the thick of it.
