A kiln explosion nearly wipes out an art class attended by Dee Dee McCall (Stepfanie Kramer). Though at first it looks like an accident, McCall receives a tape suggesting that the explosion was deliberately triggered. The subsequent murder of an EPA inspector who had been investigating reports of toxic waste dumping leads McCall and Hunter (Fred Dryer) to conclude that the intended victim of the explosion was elderly art student Emily Hill (Louise Latham)--who happens to be romantically linked with a powerful business mogul. ~ Hal Erickson, Rovi
