Harm, Bud, and Josh take part in a tiger cruise; the ship's crew "rescues" people from a raft. The newcomers are anti-Castro terrorists who seize the ship and launch missiles to hit Castro. Harm and Josh work together to help defeat them.

Palmer captures Harm and makes a mask of his face, so that he can impersonate him. Palmer, the imitation Harm, goes to a hearing, where he tries to kill a Marine officer accused of violating a weapons treaty. Bud gives Harriet some jewelry.
