The Machine That Changed the World - Season 1

Storage Wars follows professional buyers and their teams as they scour repossessed storage units in search of hidden treasure. Part gamblers, part detectives, these auction pros have found everything from coffins to the world's most valuable comic book collection, paying as little as ten dollars for items valued in the millions.

Each episode of Storage Wars follows a group of bidders as they get a quick peek inside the units, aided only by the beam of a flashlight. They then must assess on the spot if the unit is worth a bid and how high they will actually go to grasp the gold. The high-stakes fun begins as we see if the resulting buy is full of mostly trash... or true treasure.

Set in the middle of the jungle, "The Challenge: War of the Worlds 2" returns to a classic team format; 14 Brits will battle it out against 14 Americans for their share of the $1 million-dollar prize.

Mean Girl Murders explores the inner workings of cutthroat cliques, vicious backbiting and cruel intentions.

With her son grown, single mum Pearl, pursues her lifelong dream and starts a private detective agency, which she runs from her family restaurant in the coastal town of Whitstable. Drawn by her caring nature, locals soon flock to her with all kinds of cases. But when a friend dies suspiciously, Pearl finds herself in conflict with gruff new cop in town DCI Mike McGuire.
