"Cannonball" is a competition series in which contestants from across America face off in an aquatic arena full of fast and wet challenges. Each episode features 16 larger-than-life personalities willing to jump into the deep end and compete in four rounds of physical challenges -- from the speed slide Mega-Ramp to a thrilling Drop Tower to the explosive Air Cannon and more. Each round eliminates more hopefuls, until one champion remains. WWE Superstar Mike "The Miz" Mizanin and Rocsi Diaz host, while comic Simon Gibson provides color commentary from the sidelines.
