 Beach invites NYPD cop, and best-selling author, Lou Friskham-Farino (Lou Hirsch) to help the team gather enough evidence to arrest  Smiler  McCarthy. He brings with him a bag containing $500,000, and a dye that will coat the money and anyone who opens the bag. Unfortunately, Mark Kemp can t resist the temptation to see what half a million dollars looks like, and he, and most of the rest of the team, spend the rest of the episode covered in silver paint! They get information about when McCarthy is to take delivery of a quantity of counterfeit money, and stake out his house.
