A highly experienced BBC scenarist tells a sputtering story of the uneasy collaboration between Jack Regan of London's elite Flying Squad and John Ewing, out of the San Francisco Police Department, both looking for the same man although Ewing has a personal score to settle. This all ties in with some blank passports, IRA Provos and a chain-smoked series of bank robberies. Relentlessly gratifying for those that like them rock hard, stone cold.
