Detectives Reese and Crews investigate what is obviously a serial killer. On the first day, they find three steamer trunks - appropriately numbered 1, 2 and 3 - with each containing the body of a recently deceased individual. The autopsies confirm that all three were alive when they went into the trunks and subsequently suffocated in their enclosed environment. They know they have a bigger problem on their hands when a store owner tells them he recently sold 10 identical trunks to one person. The squad gets a new Lieutenant, a transplanted New Yorker.
