What do a chronic runaway boy, the three children brutalized by six others, the mother who drowns her youngster, and another father who turns on his own, all have in common? The oral contraceptive drug which was tested on a small scale in a suburban community? Or perhaps the ex-Dachau Dr. Hubschmann who takes his own life? A grand jury investigation which proceeds by testimony here, refusal to talk there, tapes, statements, speculations, will mobilize your attention and (mis) direct it, occasionally, while leaving a few afterthoughts, more than the genre usually provides along with the skillful entertainment that this is -- over before you know it or guess it or wish it were.
