A Taboo Trek of Temporal Agents

Professor Connie Gates enlists the aid of one of the college janitors, Paige, to journey back in time to rescue one of Professor Gates' colleagues, Professor Lita Carson, trapped in time in the 1st century AD. The Trip is not a direct path to their destination. They must travel in blocks of time due to the parameters of time travel, and the unique biofuel the machine requires. Things looked bleak if their first stop was a premonition of the entire trip.
Trying to get to 18th century Russia the duo misses the mark by a year and a thousand miles. Landing in the southern Balkan peninsula and encounter a lost tribe of Amazons, with rituals and customs that cause the time travelers more than a twenty-four hour very erotic delay. The delay nearly costs them their lives before they narrowly escape capture and charge back to mid-1st century Britain. The time machine's erratic behavior allowed the temporal travelers to skip at least three stops to reach their destination sooner than expected.
Once the women have landed, they are met by a mysterious figure dressed in a hooded gray robe. Uncertain of her intentions, Connie and Paige chase her away, only to find themselves captured by the queen of the Iceni tribes. The most ferocious of the Celtic tribes, who also happens to be their lost colleague, Lita Carson. They find their friend from the 21st century unwilling to return with them and even sentence them both to death the next morning.
Things look bleak for Connie and Paige, captured by the Celts and miles from their time machine will they be able to change Lita's mind or possibly escape, as time is running out?
