High Seas

One of Gibbs's former team members, NCIS Special Agent Stan Burley who is Agent Afloat on the USS Enterprise calls for assistance when a sailor suffers a meth overdose while on leave, despite the sailor in question claiming that he's never taken the drug. When another sailor is admitted to sickbay under the same circumstances, Tony and Kate investigate the source of the drugs within the crew while Gibbs begins to suspect that a senior officer on the ship is secretly doping the crew with performance-enhancing drugs.
