When wunderkind physics student Quinn (Jerry O'Connell) invites his professor and a friend to witness his latest wormhole experiment, things go awry as Quinn, his friend Wade (Sabrina Lloyd), Prof. Arturo (John Rhys-Davies) and an innocent bystander (Cleavant Derricks) are sucked in. As they struggle to find a way home, they land in various incarnations of San Francisco -- with completely different people and political and cultural situations.
