Laz is an undercover cop coming in the from the cold. He's a social outcast and a rebel who has been on the streets too long. His return to the traditional police force - and to the bombing investigation team - has explosive results. Laz doesn't rejoin the human race easily. But he proves his value beyond question when he provides the hard-pressed team with their first solid lead - a stolen car garage that worked on the bomb car. But concealing the truth of who you are is a hard habit to break.

In a raid on the stolen car garage, Nick - one of the bombers - is caught in their net. A relentless round of interrogations go on into the night. Nick keeps a very low profile. He manages to wriggle free, unsuspected. There's not a shred of evidence to connect him. He walks into the night, laughing at the police.
