Physics graduate student Quinn Mallory (Jerry O'Connell) gets more than he bargained for when he creates a device that thrusts him into a seemingly endless parade of parallel universes in this thought-provoking sci-fi series that co-stars John Rhys-Davies. As Quinn and his best friend, Wade Welles (Sabrina Lloyd), and Prof. Maximillian Arturo slide through time and space, they grapple with historical oddities, natural disasters and aliens.
