Follow nine pairs of everyday people on an epic Bond-inspired global adventure. Ten questions stand between brothers James and Joey and £1,000,000, as they face a gruelling trek across the Scottish Highlands. A familiar Rolls Royce, a race through Venice and a dramatic encounter in an Italian palazzo await.

The Bone brothers survive their close call with a boa constrictor in Venice, but did they do enough to get the question right and bank £25,000 of The Controller's money? Married couple Kamara and Josh, are hoping for a better future for their family but a terrifying and breath-taking climb put Josh's fear of heights to the test and could put an end to their dream of winning £1,000,000.

Next to enter The Controller's Bond-inspired world are emergency nurses Beth and Jen. With years of experience dealing with trauma in hospitals and warzones around the world, they prove early on they are a force to be reckoned with. With £50,000 banked, following their exploits in the Venetian lagoon, the Bone brothers find themselves dropped in the middle of the unforgiving Amazon rainforest.

The Atacama Desert, Chile. One of the most hostile places on earth and The Controller's next brutal playground for Kamara and Josh. They emerge through the heat haze desperate to bank £100,000 getting them one step closer to the £1,000,000 question. Their journey will take them on an unexpected road trip through the desert, challenging their resolve and strength both physically and mentally.

This high-octane episode sees the remaining pairs in some of the world's most iconic locations - from the secret rooftops of Venice, traversing high above the busy bazaars of Istanbul, and breath-taking jumps onto moving train in the Chilean desert. The Bone Brothers enjoy a rare moment of respite on the golden sands of Jamaica before an epic hunt for a scuttled vessel and a £200,000 question.

A million miles from their humble beginnings, on a scuttled catamaran off the Jamaican coast, the Bone Brothers face their £200,000 question. James and Sam head deep into the desert to an apocalyptic ghost town and a question which is out of this world. Following their cathartic volcanic adventure, Kamara and Josh battle through the swampy, crocodile infested back waters of Jamaica's Black River.

In the desert the £1,000,000 prize rest on a pair's knowledge of early space exploration. In Kingston Jamaica, a pair take to the seas as they search for a lost freight ship. The remaining pairs now face the £300,000 question. The Controller invites them to a luxurious, exclusive casino in a remote private villa on the Jamaican coast. They must roll the dice to face their toughest question yet.

After being dropped high in the Swiss Alps the pairs face a gruelling off-piste hike across the freezing slopes in waist deep snow to a remote ice lake. They discover The Controller has rigged a question case with high explosives. The only way to continue is to shoot it down before it detonates, and their journey is over.

Four pairs must track down the yacht of Bond villain Scaramanga (The Man with the Golden Gun). The Controller has ordered them to retrieve a hard drive. Standing between them and success is a boatload of scorpions. For the fastest pairs, there's a £25k prize. But the slowest will be faced with elimination.

Four pairs are in Bangkok for their first mission. The Controller has sent them to Sinn Sathorn Tower (Tomorrow Never Dies) to restore a satellite signal. To succeed they must climb two communications towers perched six- hundred feet above the city streets. For the fastest pairs, there's a £25,000 prize. But the slowest will face elimination.

The remaining hopefuls are in Austria. Three pairs must transport fragile components to the top of the Alps. When their cable car stops mid-air, success is a terrifying tightrope walk away. In Vienna, the others must ride a rollercoaster to locate a device then deactivate it. For two pairs, there's a showdown at the top of a Ferris wheel.

The Controller ramps up the psychological pressure. Six remaining pairs are trapped in a classified location and separated from their teammates. Their mission - escape confinement, clear hazardous obstacles and avoid booby traps to recover precious intelligence on their rivals. But what they must do with that intelligence will be their hardest task yet.

After the events of the previous mission, rivalries are at boiling point. So, the scene is set for a shoot-out. The five remaining pairs must compete face-to-face. Their weapons are duelling pistols, the target a shot glass of tequila. Succeed and they bank £100,000 but two must fight for survival in an epic gladiatorial contest.

The Controller sends the remaining four pairs to Mexico City to search for a key that unlocks a prize of £250,000. But it's the Day of the Dead and a million euphoric revellers stand in their way. To succeed they must forge alliances for the first time and, on the day that the dead return, failure leads to a showdown with a vengeful ghost.

The Controller sends the final three pairs on the most challenging mission yet dive to a shipwreck in shark-infested waters in the Bahamas to retrieve a box, the contents of which will test their 00-agent skills to the max. One pair will be eliminated. For the others, a chance to win half-a-million pounds in an all-or-nothing visit to a casino.

Six pairs have been eliminated. Just two are left standing. At the Vesper Club in the Bahamas, they must hold their nerve in a high-stakes game of cards to determine who will return to London to take on the Controller for one final mission - and a shot at the life-changing one-million-pound prize.
