Will you be able to know what is true and what is a lie? Paula Vázquez is in charge of this new contest where four celebrities must be able to trace their own path to cross a bridge. They have to step on the truths and avoid the lies. With each truth, an amount of money is accumulated that increases during the program. But each lie is expensive, reducing half of the money earned up to this point. And when three lies are stepped on, all the money accumulated is lost and also that player will be eliminated. The final prize will go to an NGO. Decisions have to be made within an exciting countdown. A panic button causes the fate of the contestants to change in an unexpected way. Will our well-known contestants be able to recognize the truths and unmask the lies?
