NCIS Season 5 Episode 14

After the corpse of René "La Grenouille" Benoit is dragged in Baltimore harbor, the whole team is shut down pending an investigation headed by Senior FBI Agent T.C. Fornell. The main suspects are Gibbs, who had opportunity during an operation with Tony and Kate, and Jethro's ex - the NCIS director, who had a motive after a private investigation of her pa's suicide and is also suspended. Fornell also interrogates Ducky and McGee, aware of their connections and plausible parts. Once they are released but forbidden to sleuth the case, Gibbs decides to 'investigate the FBI' from his home. Tony is accused of the murder after his frustrating orders to seduce daughter Jeanne Benoit.
