After Kelly turning down Ed's request for a second date seven years previously, the time line has been changed. The Kaylons have destroyed Earth and most biological lifeforms in the universe. Ed and Gordon, unaware of the change in time path, are renegades, on the run from the Kaylons. They are contacted by Kelly and the remainder of the crew. Kelly is aware how things have changed and has a plan to make it right.
