Robot

STORYLINE

When the secret plans to a disintegrator gun are stolen by what appears to have been some kind of giant robot, the newly-regenerated Doctor is quickly called in to investigate.

The trail leads to a group of right-wing scientists called Think Tank, who are seeking to use the robot and disintegrator gun to impose their edicts on humanity.

As the situation escalates, Sarah Jane may prove to be the Doctor's only means of influencing the robot.
