CAT plot
A long time ago, Gurnam Singh was a young informant, a CAT, for the Punjab Police. He infiltrated a terrorist gang that killed his parents, and helped police take down the gang during a gun deal. For his efforts, he and his brother and sister, both still small children, were given a new place to live and a new identity. Now, in 2006, Gurnam leads a normal life as a mechanic. His sister has settled in Canada, but his brother Sunny still lives there, where he is struggling in college. One night is caught selling drugs and is arrested. Desperate to have the charges against Sunny dropped, Gurnam approaches his old police contact, Shetab Singh. To get his brother released, Gurnam must once again infiltrate a large drug empire where he stumbles upon a dangerous link to his dark past.
