Gleaming the Cube does for skateboarding what Over the Top did for arm wrestling -- i.e. not a hell of a lot. Christian Slater is the skateboarding star, playing Brian Kelly, a sneering and laconic teen outcast. He feels left out and envious of his adopted Vietnamese brother Vinh's (Art Chudabala) success as an honor roll student and as the center of attention in his family. When Vinh commits suicide, Brian is suspicious and rolls away on his skateboard to find out what really happened -- and ultimately to avenge his murder. Brian's investigation is aided and abetted by a sardonic detective named Al Lucero (Steven Bauer), a collection of skateboard aficionados, and an incredibly attractive Vietnamese girl, Tina (Min Luong).
