 The team investigates two cases. The first, conducted by Grissom, Sara, and Greg, involves a dead woman found in a fountain. Although she drowned, the water found in her lungs do not match that of the fountain. The investigation leads the CSIs to a group of swingers who partied with the victim prior to her death. The second case, investigated by Warrick and Nick, involves the death of a landlord in a gaming arcade. The heavy stench in the room leads to the discovery of another body hidden in a gaming booth.
