upstairs downstairs

I know there was an episode of the TV show "Upstairs Downstairs" that included the Titanic, and that one of the characters died on the ship, but that's pretty much all I know. Can anyone give me anymore info, such as synopsis, description, etc? Thanks!

Hey all, has anyone ever seen the "Upstairs, Downstairs" episode where Lady Marjorie Bellamy travels aboard and goes down with the Titanic. Can those of you who have seen it tell me whether the episode was actually set on the ship or was it set in Eaton Place when the devastating news reached...
