In each episode of Guy's Grocery Games, four talented chefs compete in a number of challenges as they navigate their way through the aisles of a grocery store, adhering to "real-world" obstacles. Whether it is shopping on a budget, substituting out-of-stock ingredients or grabbing groceries at closing time, each chef has to shop, prepare, and plate three different dishes using whatever they can pull off the shelves. Ultimately, the food does the talking, as one-by-one the losing chefs "check out," by a rotating panel of judges that includes Melissa d'Arabian, Richard Blais, G. Garvin, Troy Johnson, Catherine McCord, Aarti Sequeira, among others. The last chef standing goes on a shopping spree of a lifetime worth up to $20,000!

SurrealEstate revolves around real estate agent Nick Roman and an elite team of specialists who handle the cases that no one else can: haunted and possessed houses that literally scare would-be buyers away. Researching, investigating and "fixing" the things that go bump in the night, the team works to create closure — and closings — as they struggle with demons of their own.

In any given year, more than 600,000 people are reported missing in the U.S. More than half that number are people of color that the country seems to forget about. Public relations specialist Gabi Mosely - who was once herself one of those forgotten ones - and her crisis management team now make sure there is always someone looking out for the forgotten missing people. But unbeknownst to anyone, this everyday hero is hiding a chilling secret of her own.

Detective Charlie Hudson, a cunning Major Crimes detective for the St. John's Police Department, teams up with an unusual partner – Rex, a former-K9 German Shepherd, whose heightened senses keep Charlie hot on the trail of his suspects. Together, they investigate puzzling crimes, from a kidnapping which reveals a much larger conspiracy at play to an art theft murder which runs deep into the world of high society. With Charlie's deft detective work and Rex's keen canine senses, this crime-fighting pair is unstoppable.
