“The Closed Night” has been the most listened-to late-night radio show for decades, hosted by Luis Gálvez, the most respected broadcaster in the country. Luis takes calls from people in distress and always finds a way to help. But tonight will be different. A man named Salvador is on the other end of the line and plans to end his life. He sets strict rules: the host cannot leave the live broadcast, cut the call, or step out of the booth. A macabre game of blackmail and escalating tension begins. Luis is not who he seems to be, and someone has decided to make him pay for it.
