Legend has it that when the country needs it most, a "Silver Soldier" appears to save it. Silver Sun is the silver soldier of our times, who a year ago saved us from a new coup d'etat by Gral. Rodriguez. Now, turned into a public servant, a vacuum torments him and that is that he does not remember his past. Nobody knows him and nobody has, only one idea resonates in his head: serve and protect.
Silver Sun coordinates the security of the hotel where the MERCOSUR summit will take place. Super Heroes from all the delegations arrive in Mar del Plata to protect their top leaders when Sun receives a mysterious call that promises to reveal his past.
