Sabine

 worked on the Excelsior. She was on board when hijackers took over the ship, hoping to capture or kill the Draconian ambassador. The Eighth Doctor helped Sabine get to an escape pod.

Sabine landed on a colony planet where she met Lucie Miller. Together, they followed clues left behind by the Doctor so they could defeat the hijackers, who had also landed on the planet, and rescue the hostages. (PROSE: Decorative Purposes)
