At a time when partisanship in U.S. politics litters the media landscape, Discovery Channel's "RIVAL SURVIVAL" brings together two real world political adversaries and maroons them on a remote island for a week. Disconnected from the world on an uninhabited island surrounded by shark infested waters that mirror the seemingly treacherous terrain of the U.S. Congress, Sen. Jeff Flake (R-AZ) and Sen. Martin Heinrich (D-NM) must put their political differences aside and work together for six days and six nights to find common ground through compromise if they want to survive in RIVAL SURVIVAL which premieres on Discovery October 29 at 10PM ET/PT. / Sen. Flake, a true conservative Republican, served in the U.S. House of Representatives for six consecutive terms from 2001-2013 prior to his election to the U.S. Senate. Sen. Flake is a self-described reformer who attacks government spending and is vocal on hot-button issues like immigration reform. Last year, Sen. Flake and Sen. John McCain (R-AZ) were part of the "Gang of 8" who teamed up to try to change immigration policies in the U.S. Sen. Heinrich, a member of the Senate's Energy and Natural Resources Committee, is a self-described conservationist and a strong progressive voice from New Mexico on issues that include education, health care and social security. Polar opposites and often at odds in the Senate, these two men must come together to take on the island of Eru, Marshall Islands, an utterly unforgiving deserted destination where the reefs alone are fraught with dangers that include venomous stonefish, lionfish and scorpion fish. / In RIVAL SURVIVAL, our senatorial adversaries turned survival teammates are given a modest choice of items from which they can select only three. Using only these limited resources and their wits, the pair must work together as they attempt to spear fish, build shelter and find enough water to survive for one week. There is no natural source for fresh water on Eru, and what lives in the ocean will be their major food source. This unusual pairing will leave behind the daily life of congressional staff, senate hearings and committee meetings to navigate the rigors of surviving on an isolated island with no contact with the outside world to call upon for help. / Once a pivotal point of control during World War II, Eru is home to the wreckage of downed WWII aircraft, and is also knows for what lurks in its waters -- the largest shark sanctuary in the world with more than 2,000,000 square miles of protected waters. The ban on shark fishing here has created one of the greatest shark populations on earth with nearly every major species of shark, including Black Tip Sharks, Oceanic White Tip Sharks, Grey Reef Sharks, Bull Sharks and Tiger Sharks, among others.
