In the episode, the two investigators are in danger when Caruso's character, Horatio's old enemy, Clavo Cruz, returns. An explosion occurs sending a truck full of confiscated weapons onto its side. Weapons spill out all over the street and are scooped up by the public, Horatio links the crime to Cruz, who he put away for murder years ago.
On the day of Cruz's arraignment, a confiscated missile is launched into the courthouse to aid his escape, with an investigator inside. When the team tries to find Cruz, Horatio and Eric, played by Rodriguez, wind up in a shootout. A gun battle ensues and Eric is shot.
"We come close to losing him and it takes us two hours, two Monday nights to fix the story and get him back to health and, thank God, we do because he's very important to us," Caruso said.http://www.cbsnews.com/stories/2007/02/05/earlyshow/leisure/celebspot/main2431611.shtml
