Richard Hammond hosts another episode of TV's stupidest, brightest, most insane game show. In this series the obstacles have been made bigger and brasher than ever, ensuring bigger and brasher bumps, crunches, smashes and splashes. Richard's co-host Amanda Byram is course-side in Buenos Aires as 20 over-excited Brits tackle the purpose-built Argentinian obstacle course. Will their bodies and dignity hold out long enough to capture that 10,000 pounds first prize, or will they be wiped out by the Sucker Punch, Crash Mountain or, worst of all, the dreaded Big Red Balls?
