Ace is pretty excellent when you first meet her, and she is dealing with a smarmy "I want to be Han Solo but I'm too middle-aged" smuggler named Glitz, the Doctor's current companion Mel (of an amazing scream) and... well, lots of stuff, really.

So I'd suggest start with the 7th Doctor serial Dragonfire and work your way along from there, and enjoy the horribly out-of-date slang she uses.

Also, her run with the 7th Doctor contains some really, really trippy episodes.

I couldn't find anything on YouTube except for this clip of Dragonfire, sadly. No explosions.
