The team investigates why three volleyball players mysteriously dropped dead right after an exciting game, and Horatio notices that all three of them had burn marks under their feet, which leads the team to believe they were all electrocuted from wires in the sand. However, Calleigh and Jesse follow the wires, but end up on a dead end. Meanwhile, Calleigh and Delko testify their stories about the situation where Delko was shot last season (episode 725), and Ryan fears that they both might lose their jobs.
