When a case proves too baffling for the minds of Interpol, they turn to the talents of Department S.

Two men, one woman - three extraordinary agents. Jason King (Peter Wyngarde): an eccentric novelist; Stewart Sullivan (Joel Fabiani): a determined man of action; Annabelle Hurst (Rosemary Nicols): a meticulous computer expert. Each with their own distinct method of approaching an unsolvable and bizarre crime, the team of DEPARTMENT S proves that the most illogical of situations has a logical explanation. ITC mystery-action favourite comes to Imprint Television, with every episode digitally restored from the original 35mm elements! Ahead of its time, Department S was a forerunner to contemporary series such as The X Files, adored by viewers and resulting in the hit spin-off series Jason King.
