Arriving at the scene of the brutal murder of a college girl, Hooker recognises the method of murder as used by a serial killer dubbed ""The Night Ripper"", who was behind a spree of six grisly sex murders four years previously and was never caught. With the psychotic killer terrorising the city once more, Hooker is under pressure to uncover his identity and get him off the streets... An average episode at best, though it's still watchable but it's flat in places and not too tense. And it also sleazier than usual with a killer mutilating his victims. There are the usual red herrings - the wrong person gets caught.
