Atlantic City may be a nice place to visit, but it's hell to police, as Vice detective Louis Monroe (Under the Boardwalk, 1988) keeps getting reminded. Taking time out from his preparations to marry former call-girl Ellen Meade, impossibly idealistic Monroe busts hated fellow-officer Reuben Claymore for drug dealing, only to find that he's unleashed an unlovely gaggle of politicos and cops--each dying to bring each other down. Inspector Ephrum Traile, head of Internal Affairs, orders Monroe to wear a wire to gather evidence against his corrupt new partner, Sgt. Ray Deegan, who's out to get state cop Wayne Zimmer, who's out to get mayor Bernie Tilton. The plots and counterplots all end up revolving around a child stolen from a former Miss New Jersey 30 years ago--and, yes, both mother and baby turn up with surprising new faces. As unlikely a premise as one of Jon Jackson's tough Detroit procedurals with Candide sitting in for Fang Mulheisen. But taken scene by scene--as Kent shows the rescue of a beached whale, an unbelievable slot-machine payoff, and several fistfights with a 300- pound dominatrix--an impressively imagined entry.
