Set in a fictional version of London. James Blood is a hot-blooded officer working for the elite "Special Service of Crime" (SSC) division within the Capital Police Department. Sarah Sinclair is a subordinate to Crown Prosecutor Monica Campbell, whose witness suddenly drops dead while working on a high-profile case involving the LIVE Corporation.
