Hung out to Dry

A Marine dies during a night-time training jump. The culprit seems to be a faulty parachute, but the standard investigation reveals that the death might not have been an accident after all. Gibbs begins to believe that the supposed accident which resulted in the Marine's death might actually be murder after all and he and Tony, along with new recruit Kate Todd, set out to find out who tampered with the dead Marine's faulty parachute and eventually sent him to his death.
