Battle Lines starts with Stingray's final epic storyline from TV Century 21. From there, the anthology includes Stingray's adventures from the pages of Countdown in the early 1970s involving underwater tremors, cyber saboteurs and Martian monsters, plus the standalone adventures from the seasonal special editions of TV Century 21; Marina, Girl of the Sea from Lady Penelope; and the episode adaptations from the 1990s Fleetway comics.
