Scandal rocks the Bayport police force! New commissioner Mark DeCampo has suspended veteran police chief Ezra Collig, saying he has proof Collig was once a bagman in a bribery scheme. Now Collig is on the run, and when DeCampo barely survives a car bomb, the chief is accused of attempted murder!

The Hardys have had differences with Collig in the past, but they refuse to believe he's a dirty cop. The boys head to Millerton, the town where Collig began his career, and expose a 35-year-old police cover-up. But they also stir up a new case -- a case of deceit, dishonor, and danger that leads straight back to Bayport!
