The Night Agent is a sophisticated, character-based, action-thriller centering on a low-level FBI Agent who works in the basement of the White House, manning a phone that never rings — until the night that it does, propelling him into a fast-moving and dangerous conspiracy that ultimately leads all the way to the Oval Office.

The doctors of Grey Sloan Memorial Hospital deal with life-or-death consequences on a daily basis -- it's in one another that they find comfort, friendship and, at times, more than friendship. Together they're discovering that neither medicine nor relationships can be defined in black and white. Real life only comes in shades of grey.

When revolutionary Dr. Hari Seldon predicts the impending fall of the Empire, he and a band of loyal followers venture to the far reaches of the galaxy to establish The Foundation in an attempt to rebuild and preserve the future of civilization. Enraged by Hari's claims, the ruling Cleons – a long line of emperor clones – fear their grasp on the galaxy may be weakening as they're forced to reckon with the potential reality of losing their legacy forever.

The Rookie is inspired by a true story. John Nolan is the oldest rookie in the LAPD. At an age where most are at the peak of their career, Nolan cast aside his comfortable, small town life and moved to L.A. to pursue his dream of being a cop. Now, surrounded by rookies twenty years his junior, Nolan must navigate the dangerous, humorous and unpredictable world of a "young" cop, determined to make his second shot at life count.

Reacher follows Jack Reacher, a veteran military police investigator who has just recently entered civilian life. Reacher is a drifter, carrying no phone and the barest of essentials as he travels the country and explores the nation he once served. When Reacher arrives in the small town of Margrave, Georgia, he finds a community grappling with its first homicide in 20 years. The cops immediately arrest him and eyewitnesses claim to place Reacher at the scene of the crime. While he works to prove his innocence, a deep-seated conspiracy begins to emerge, one that will require Reacher's keen mind and hard-hitting fists to deal with. One thing above all is for sure: They picked the wrong guy to take the fall.
