Nelle profondità dell'oceano

A request for intervention arrives at Agenzia Alfa from the underwater scientific station Atlantis: the reason for the call is not specified, but the dispatch of Nathan Never is expressly requested. Once on site, the Special Agent begins his investigations and immediately realizes that something serious has happened: in fact, beyond the four members of the team connecting with the surface, who have no contact with the inside of the station, the laboratories are completely deserted... A dark threat weighs on all of humanity and only Nathan and a mysterious mutated girl named Ysha can try to avert it!
