 The part of the city which has the highest crime rate is under the care of Captain Pete Lassard, when the chief demands that he turn things around or he is out. He in turn calls his brother, Eric, the academy commandant, and requests some new people. He recommends recent graduates, Mahoney, Hightower, Jones, Tackleberry, Fackler, and Hooks. Now they are teamed up with some veteran officers, who are not exactly competent, and along with their inexperience they cause more trouble than the gang they are pursuing. And they also have to deal with Lieutenant Mauser, who wants them to fail, so that he could become the new Captain.
