Plot
When a Senator is killed in an explosion, the FBI investigates. The agent in charge is bomb expert Danny O'Neill, who is separated from his wife Terry (due to the accidental drowning of their only child in their pool) and behaving very erratically. Initially the investigation does not reveal the kind of explosive used or even what was used to detonate it. Eventually it is learned that terrorists led by Mikhail Rashid have developed an "invisible" liquid explosive which is activated within the human body (by stomach acid). It also does not help that they have to report to Senator Traveres, the man whom Terry is having an affair with and whom Danny also assaulted.
Later, another senator is killed while riding in a limousine; the limo being driven by one of Rashid's henchmen. The henchman is subsequently struck by a moving car, taken into custody and brought into court, and since he is now considered a risk by Rashid, the judge in the case is slipped the liquid and she spontaneously explodes; the witness is subsequently killed, though O'Neill discovers the cause of the explosions - the chemically enhanced water in the judge's pitcher.
It becomes obvious that the next target is Senator Traveres, so O'Neill, concerned that Terry may become collateral damage, trails his every move. At a fundraiser, Traveres is targeted by Rashid's main henchman, Al-red, who is disguised as a clown. Al-red tries to detonate a fountain filled with the explosive liquid, but O'Neill tackles him, leading to Al-red accidentally swallowing some of the liquid himself. O'Neill subdues Al-red and gets him away from party in a wheelchair just before he explodes. In the aftermath, O'Neill and Terry finally reconcile.
