When a vital piece of evidence goes missing from the station, Tom has to face the unpleasant prospect that one of his team might be corrupt. As the accusations fly, Monica Draper arrives to conduct an investigation. Both Adam and Dash comes under scrutiny—both have a connection to the case and both had the means and opportunity. The stolen evidence, a videotape, incriminates Dash's ex-teacher—a woman who had a profound influence on Dash and convinced her to join the force. Could Dash have acted to protect her mentor? Adam's close connection to local businessman and politician Doug Healy also makes him a suspect. Did Doug pay Adam to break into the station and steal the evidence? The case against Adam looks particularly grim when Dash discovers the stolen videotape in his car. He insists the evidence was planted by Healy. The Heelers want to believe him, but the seeds of doubt have been sown. Meanwhile, a burglary victim reveals that not only is his stereo missing but $250 in cash.
