Timothy Hutton and Vanessa Williams star as FBI agents in a thriller about a biological attack on the U.S. The attackers: a loosely linked band of Arabs and Russians. First, a Lebanese national releases a "hot virus" aboard a cruise ship off San Diego, killing 1500. Then an Iraqi does the same in a Chicago ballpark. And a Russian with a similar idea is on the loose in D.C. The FBI had better work fast because, as a formerly Soviet bioengineer puts it, certain death is spread "cough by cough."
