David Jason stars as unconventional policeman Detective Inspector Jack Frost, whose arrogance and indifference to orthodox police procedures masks a keen sense of observation and a dedication to solving crime. Based on the books by R.D. Wingfield, each feature length episode shows Frost unravelling complex cases with his special touch of sharp instinct, dogged determination and compassion.

Line Of Fire
Frost's festive season gets off to a bad start when a regional Crime Squad detective is found murdered on his patch. The evidence points to police corruption, and when Frost instinctively takes the lead in the subsequent investigation, he clashes with the dead policeman's abrasive boss, Chief Superintendent Finlay.

Benefit Of The Doubt
Frost is teamed up with a new partner and they find themselves working an unpleasant murder. His detective skills face a tough challenge when he is caught up in a case of mistaken identity, a missing doctor involved in the death of a young boy on the operating table and a surprise from his own past.
