TVLine describes the new NBC TV show "Believe":

"Levitation, telekinesis, the ability to control nature and even predict the future... Since she was 2 years old, Bo (Johnny Sequoyah) has had gifts she could neither fully understand, nor control. Raised by a small group known as the "True Believers," the orphaned girl has been safeguarded from harmful outsiders who would use her forces for personal gain. But now that she is 10, her powers have become stronger and the threat has grown more dangerous. With her life and future now in jeopardy, the "Believers" turn to the only person they see fit to be her full-time protector. That is, once they break him out of jail.

Tate (Jake McLaughlin), a wrongfully imprisoned death row inmate who's lost his will, is initially reluctant until he witnesses one of her extraordinary abilities. Bo sees people for who they truly are... and who they may become. Tate and Bo begin their journey, one in which trust must be earned. Traveling from city to city, every place they stop and everyone they meet will be changed forever. But they'll have to keep going to stay one step ahead of the sinister forces after Bo's power... because it will take a miracle to keep them safe forever. "Believe" also stars Delroy Lindo and Kyle MacLachlan.

Writer, director Alfonso Cuaron ("Children of Men," "Harry Potter and the Prisoner of Azkaban"), Mark Friedman ("The Forgotten"), J.J. Abrams ("Revolution," "Star Trek: Into Darkness") and Bryan Burk ("Lost," "Fringe") serve as executive producers. "Believe" is produced by Warner Bros. Television and Bad Robot Productions."
