[1] In August 2017, the series was renewed for a second season with applications closing by 8 December 2017, with the season airing on 12 August 2019.
[2][3] The series sees participants make a pledge to attain a personal life goal (such as losing weight or starting a new career) that they will then attempt to achieve over the next year.
The participant then appears to leave the set and then return moments later with one year having passed, the transition made seamless through editing.
They are then interviewed about what they have achieved and the challenges they faced during the past year.
