The space-time continuum will never be the same again!

The crews of Captain Jean-Lucy Ricardo and Captain James T. Smirk blunder through the timeline to retrieve a videotape accidentally transported into the future — which has spawned a bizarre “wrekkie” cult of U.S.S. Endocrine crew wanna-bes.

Aghast at the prospect of being idolized at a wrekkie convention, Ricardo, Mr. Smock and their fellow “Cons” want to confiscate the tape and prevent the wrekkie movement from ever happening… while Smirk and the other “Pros” hope to encourage the wrekkies, and soak up their share of fan worship.

As they rewrite history in visits to the Civil War and World War II, and reshape the future through encounters with the evil Bored and lost crewmate Yasha Tar, the cosmic question becomes: how much timeline can these two teams rewrite, anyway?
