After the revelation that Rafa not only works as cyber security technician for important high-tech companies but he collaborates with the global anti-system movement Anonymous, Rafa makes an explosive declaration: he claims to have decrypted the famous Julian Assange's Insurance Files and did read the information hidden in it. Reluctants to believe him Rafa gives David, who works in R&D, his cell phone to watch an App of Augmented Reality which design was in the Files.
Realizing that the App is capable to see 30 seconds in the future, shock spread everyone: Sara panics fearing the consequences of it, Eva and Ricardo suggest report it to the authorities, and Julia makes a secret call of her company, trying to take advantage of it. After Rafa explains that the App is limited to 30 seconds due to the source code, Mónica turns on her laptop and connects Rafa's cell phone to it, in an attempt to check and alter the code to overpass the limit of 30 seconds.
But when finally Mónica, David and Rafa succeed after a few failed tries, all they disclose an endless horror that it could to have disastrous consequences for human race.
