A loving father finds a clown suit for his son's birthday party, only to realize the suit is part of an evil curse that turns its wearer into a killer.
The show takes place from 1944 to 2002 and follows the lives of three families: the Crawfords, who seek to cover up the Roswell crash and the existence of aliens; the Keys, who are subject to frequent experimentation by the aliens; and the Clarkes, who sheltered one of the surviving aliens from the crash.
