Frank Minna is a Brooklyn PI with ties to the mob. Years ago he had rescued 4 boys from a local orphanage and given them jobs. Now they are his Minna Men. Lionel is on a stakeout when he witnesses Minna's murder and he decides it is his duty to find the killer.
Only problem, Lionel suffers from Tourette's syndrome. Tourettes doesn't keep him from solving the mystery but it sure makes for interesting conversations and interactions.
