The town of Roswell, New Mexico, has been haunted for decades with accounts of a looming alien presence. The popular television series ROSWELL takes that concept one step further, as aliens become everyday teenagers. Four alien-human hybrids (Shiri Appleby, Jason Behr, Katherine Heigl, Brendan Fehr) have been sent to Earth to wait for the day when they'll return to their planet and save their race. Season Three sees the finale as their fates are decided after the shock departure of Tess in the previous series..
