Everything is in order: the first course is ready, the roast is in the oven and the table is set. Without a doubt, this is going to be a gathering of true friends and the waiting comes to an end when the first couple arrives. The bell rings and it is Lele and Carlotta, followed subsequently by Cosimo and Bianca; the only one missing is Peppe, their friend who is still single. Before long, the group is complete and without any delay, they begin the feast. Surely, this is a nice but somewhat usual dinner, when suddenly someone makes a proposition: to place their mobile phones on the table and like a Russian roulette, whatever arrives (texts, WhatsApp messages, calls) they would share it with the others. Clearly, this uncommon truth or dare game has no point among friends who share everything with each other, nevertheless, when the phones start ringing, who will be the one with the sweatiest palms?
