Al Hayba - Season 2

Poker Face is a 10-episode "mystery-of-the-week" series following Natasha Lyonne's Charlie Cale, who has an extraordinary ability to determine when someone is lying. She hits the road with her Plymouth Barracuda and with every stop encounters a new cast of characters and strange crimes she can't help but solve.

In this workplace comedy, a group of dedicated, passionate teachers — and a slightly tone-deaf principal — are brought together in a Philadelphia public school where, despite the odds stacked against them, they are determined to help their students succeed in life. Though these incredible public servants may be outnumbered and underfunded, they love what they do — even if they don't love the school district's less-than-stellar attitude toward educating children.

Based on an international hit, which already is a viral phenomenon with more than half a billion fans worldwide, and the No. 1 top-trending video of 2017 on YouTube, The Masked Singer features celebrities facing off against one another with one major twist: each singer is shrouded from head to toe in an elaborate costume, complete with full face mask to conceal his or her identity. Ken Jeong, Jenny McCarthy, Nicole Scherzinger and Robin Thicke serve on the panel and play detective, alongside host Nick Cannon.

Zero Day asks the question on everyone's mind — how do we find truth in a world in crisis, one seemingly being torn apart by forces outside our control? And in an era rife with conspiracy theory and subterfuge, how much of those forces are products of our own doing, perhaps even of our own imagining?

NOVA brings you stories from the frontlines of science and engineering, answering the big questions of today and tomorrow, from how our ancestors lived, to whether parallel universes exist, to how technology will transform our lives.
