Period drama series. In the 19th Century determined James Onedin starts his own shipping line based in Liverpool. Grew out of a Drama Playhouse entry of 1970 and over the years there were many cast changes as Onedin's empire grew but the show remained a popular Sunday evening staple throughout its run.

So far as I am aware Michael J Bird contributed only this one script.

About which the Onedin Line Appreciation site said ...

"Elizabeth's pregnancy is kept a closely-guarded secret by her family, but she cannot bear to give up the attentions of wealthy Albert Frazer. James and co must save the Charlotte Rhodes, which is on fire, but can they arrive before the Callon vessel looking to salvage the ship? There's also a score to settle between James and Fogarty on the latter's return..."

Comment - Brilliant. Exciting sea chase in Albert's steamer, and the best fight scene in the entire series. The scene with the trio of James, Robert and Albert setting out to retrieve the stricken Charlotte Rhodes works really well.

You can view a selection of screencaps from the episode at the Anne Stallybrass & Peter Gilmore website.
