A group of strangers come together to form an elite team of operatives after time travellers overtake their conscious minds.

In an effort to complete their first large-scale mission, the team realises that no plan survives contact with the past. Their fatal mistake now has the team holding on to a ticking time bomb.

As the travellers adjust to life in the 21st century, one team member buckles under the guilt of not being allowed to prevent future deaths, putting our entire team in jeopardy.

MacLaren's leadership is challenged and the team's alliances are questioned when they're directed to assist a more experienced team of travellers. Perhaps being a traveller in the 21st is more dangerous than they thought.

After a routine traveller mission the team is ambushed and imprisoned by sinister forces. MacLaren is on his own as he fights to unravel the mystery of his team's sudden disappearance.

The day of the primary mission has arrived and travellers from all over the country join forces to stop the cataclysmic event that will change the course of human history... but will it be enough?
