SUMMER OF SAM, Spike Lee's sizzling interpretation of the summer of 1977 in New York City, when thermometers shattered and a serial killer terrorized the city, focuses on an Italian-American community in the Bronx--specifically, Dionna (Mira Sorvino) and Vinny (John Leguizamo), a couple whose marriage is threatened by Vinny's obsession with other women. After Vinny returns home one night to find a killer has murdered two local women, he promises to mend his cheating ways, albeit unsuccessfully. As the media exploits the murders and a blackout threatens to unleash anarchy on the city, its inhabitants begin to look for a scapegoat who will release them from the reign of terror created by the chilling figure known only as the Son of Sam (Michael Badalucco). Lee's ambitious film does more than re-create the events that unfolded during the summer of 1977; in addition to being an entertaining time capsule, it also deals graphically with the concept of the mob mentality.
