John Moore is persuaded into taking the newly married, 23 year old, 79 AD, Ancient Roman couple back to modern day San Francisco, 1963, in the time machine, for the mother of all honeymoons with intent of sending them back to 79 AD Rome in two weeks.
The time machine malfunctions and sends the young, 23 year old Roman newly weds, Glacus and Ruth, into the year 3000 AD.
Roman Honeymoon is then about what happens to Glacus and Ruth in the year 3000 AD, three thousand years in to their future.
