The Emperor determines that the Ogron must be shown to the Earth authorities, but as a Draconian ship would be shot down, the Prince, the Doctor and Jo will take the Master's police ship. As they cross the frontier into Earth space, they spot another ship following them. However, by the time they identify it as the Ogron ship, it has already launched its missiles. As the Doctor takes evasive action, the captive Ogron breaks out of its cell, overpowering its Draconian guard. It enters the flight deck and in the struggle cuts the ship's speed. The Prince and the Doctor subdue the Ogron, but the Master's ship catches up and a party boards the police ship. A firefight breaks out on the flight deck, just as an Earth battlecruiser shows up. The Master recalls the boarding party, who take Jo captive along with rescuing the Ogron prisoner, and their ship zips away. The Earth battlercruiser places the Doctor's ship under arrest.
