Trapped in a time and place not their own,
two strangers find the only thing they can count on is one another.
It begins when an American fighter jet is discovered submerged in Scotland's Firth of Clyde. Clearly it has been there for centuries. Clearly, that is impossible.
British reporter Lindsay Pawlowski is sent to cover the story. But Alex MacNeil, the arrogant American pilot she interviews, dismisses it—and her—out of hand.
Then MacNeil's jet, with Lindsay aboard, crashes into the water after passing through a fiery vortex that appears out of nowhere. Lindsay and Alex bail and parachute to the ground as the plane goes under—and they encounter a group of mounted men, wearing armor, bearing swords.
To stay alive, Alex and Lindsay must tread carefully; the Scotland of Robert the Bruce is a dangerous place, particularly for a woman alone. So Lindsay plays squire to Alex's knight as they slowly adjust to their fate.
