Host Phil Keoghan invites 13 former Big Brother players to compete on a journey around the world with their loved ones on the 38th season premiere of The Amazing Race.

Teams depart for Prague, Czech Republic, where they encounter a Roadblock requiring them to walk across a narrow plank hundreds of feet above ground at the city's tallest landmark, the Žižkov Television Tower, to retrieve their next clue.

The first team to arrive at the "Driver's Seat" must make an important decision that could impact the outcome of the roadblock.
