When investigating a new planet there's been a problem with the Teleporter. The Yeoman has grown to 50ft tall... Protocol would dictate attempting to put things right... but, putting things right - well - when there's crew that have been so awful to the Yeoman. Be it sending them on the dangerous missions, sexually harassing, mocking the appearance... setting quite frankly sexist uniforms. Using the size advantage - how will the crew be dealt with - blown away? crushed? swallowed whole? or devoured and crushed in underwear? Or, as the crew have been plucked from the ship - teleporting back to the ship would return the Yeoman to the normal size... but keep the crew shrunk permanently... things can change.
