The second entry in this Nigel Kneale-scripted TV series is not up to Episode 1: the main culprit is an extremely silly (albeit amusing) premise of a side-show owner being haunted by the ghost of a dolphin he mistreated because of its individualism!
As the story opens, the place has just been bought by lead Martin Shaw which he intends to convert into a porn cinema (cue some surprising nudity)!; the former owner is anxious to close the deal, so he can be rid of it and its memories, but Shaw wants to bring his own experts to evaluate the lot. Further complications arise when a waif who had once been an employee there (but who had a special relationship with Buddyboy, the star dolphin which was killed) is discovered still hanging near the pool area. Shaw is drawn to her passionate yet fragile nature and she recreates for him the introduction to a typical dolphin show; however, when they get together for the night in his apartment (soon after the definite sale of the property), the girl seemingly under the influence of Buddyboy drowns herself in the bath-tub
The episode is more notable for its realistic detail the seedy locations populated by amoral characters with thick working-class accents than the rather insufficient and, consequently, muddled fantasy/animal aspect; I actually expected the girl to turn into Buddyboy at the end or something: incidentally, the appearances of the dolphin itself (apart from the occasional disembodied 'voice') are restricted once again, presumably, for budget-related purposes to just a couple of brief silhouetted instances!
