Escape from B Movie Hell

If you asked Andi Turbot whether she had anything in common with Flash Gordon she'd say no, emphatically. Saving the world is for dynamic, go-ahead, leaders of men and while it would be nice to see a woman getting involved for a change, she believes she could be the least well-equipped being in her galaxy for the job.
Then her best friend, Eric, reveals that he is an extraterrestrial. He's not just any ET either. He's Gamalian: seven-foot, lobster-shaped and covered in Marmite-scented goo. Just when Andi's getting used to that he tells her about the Apocalypse and really ruins her day.
The human race will perish unless Eric's Gamalian superiors step in. Abducted and trapped on an alien ship, Andi must convince the Gamalians her world is worth saving. Or escape from their clutches and save it herself.
