Security teams at Peru's biggest airport work 24-7 to stop illegal activity. The biggest problem: cocaine smuggling. A woman's bag is flagged in the x-ray area but she's already been inspected twice. Police must decide whether to tear the bag apart or let her go. An Italian man claims not to understand the police. He may be telling the truth. Or he may be trying to evade the law. A shipment of children's toys may hide a stash of cocaine.
