Unpleasant doings in the London underground--mixing juvenile sentimentality with grimy sex-and-violence. Termed redundant after 37 years in civil service, Arnold Godfrey spends his time on the London tubes, slipping into senility. . . till he runs into three kids--little Elsie and teenagers Sarah and Martin--who live on the tubes. So Godfrey sort-of adopts the kids, taking them to a secret, underground government shelter. . . as melodramas ensue. A gang of rape-minded Skinheads spots Sarah and, in a truly foul scene, she chars the sex organs of one Skinhead with a flare pistol. The children kidnap Darren, a disturbed toddler whom they love. Martin is blackmailing Sarah's real father (she doesn't know she's illegitimate) for money to help set the kids up anew. And, finally, the castrated Skinhead returns to rape Sarah with a dildo--so Godfrey gets stomped to death saving her. All in all: something like YA pulp-pome--and appalling.
