Chicago kickboxer Ron Shade's knight errantry sometimes misfires in his second appearance (after 2002's A Killing Frost
) from Illinois police sergeant Black, but the throwback PI goes the distance. Shade's work, which includes stints providing security for a downtown hotel and its two bars, doesn't interfere with his ambitious goal of winning the heavyweight kickboxing championship. But his proclivity for rescue work, ranging from an old girlfriend to a stray kitten to a Russian boxer in thrall to a gangster, throws a serious monkey wrench into his plans. Shade's old high school flame, Paula Kittermann, re-enters his life in dramatic fashion, only to become a hit-and-run victim soon after. When Paula's beautiful cousin, whom he remembers as a freckle-faced youngster, asks his help in finding the driver, Shade can hardly refuse. While the supporting cast, among them a crusty trainer, a cop buddy and a cop enemy, is fairly standard issue, Shade himself is an attractive blend of tough guy and sentimental softie. One gets the feeling that Shade may never take top honors in the ring, but he'll always be an entertaining fighter as long as he answers the bell. (Apr. 21)
