Eric Delko's life hangs in the balance, having been found in the Glades, barely alive. He immediately went into surgery to remove the bullet that remained in his head from the first time he was shot and slips into a coma after it's completed successfully. We flashback to 1997 and how the team came together, with Eric, a salvage truck driver, finding a submerged car with a dead woman inside. He calls Detective Horatio Caine who comes to investigate with the help of Calleigh Duquesne, on her first day at the Special Investigations Unit. Back then, science took a back seat to on foot detective work but with the help of Calleigh, a young tech Natalie Boa Vista and Jesse Cardozo, on his last day, they figure out who was responsible for the murder of the woman. It turns out that she was being stalked by her gardner. Even though her husband looked good for the crime, through blood DNA analysis, Horatio finds a match and can place the gardner with the woman. Eric finally wakes up at the end of the episode with Horatio, Calleigh and the rest of his CSI team by his side.
