Masters of Illusion
In Masters of Illusion, the world's greatest magicians and illusionists perform magic in front of a live studio audience. There are no camera or computer tricks involved and you'll see tricks such as women turning into tigers, birds appearing from nowhere and sleight of hands in the blink of an eye! From one amazing trick to another, the performances are shown to you non-stop in a spectacular show filled with reality-twisting, mind-blowing magic.

Bar Rescue
Bar Rescue follows Jon Taffer, one of the country's top restaurant and bar consultants, will give failing establishments one last chance to succeed. The show will delve into every business facet of running a bar from creating a profitable drink/food menu to crowd management to music selection to managing disgruntled employees. This marks the first food/beverage-themed show for Spike TV, furthering its effort to expand and broaden its audience.

Naked and Afraid
Each week on Naked and Afraid, a new pair of complete and total strangers - one man and one woman - will find themselves stranded in and, quite literally, exposed to one of the world's most extreme weather environments. This duo will be left high and dry with no food, no water... and no clothes. They must survive on their own for a full 21 days, with nothing but one personal item each and the knowledge that the only prize is their pride and sense of accomplishment.
