Space, the final frontier. These are the voyages of the starship Enterprise. It's five year mission: To explore strange new worlds, to seek out new life and new civilizations. To boldly go where no man has gone before.
(Act One)
Captain's log, supplemental entry. Two drops of cordrazine can save a man's life. A hundred times that amount has just accidentally been pumped into Doctor McCoy's body. In a strange, wild frenzy, he has fled the ship's Bridge. All connecting decks have been placed on alert. We have no way of knowing if the madness is permanent or temporary, or in what direction it will drive McCoy.
(Transporter room - McCoy enters, knocks out the Chief very quickly and scientifically, then beams himself away)
(Bridge)
Kirk: Continue alert, decks four through eleven. The medical department knows as little as we do. In dosages approaching this, there's some record of wild paranoia.
