The SWAT team scours the city in search of an elusive assassin named Bravo (Christopher George). Although under normal circumstances the situation would be tense, indeed (the life of a prominent senator is at stake), and on this occasion the team is racing against time in more ways than one: Unbeknownst to himself, Bravo has contacted a deadly and highly contagious disease. Comedienne Rose Marie makes the first of several guest appearances as Hilda.
