Is El otro lado coming back?

Nacho Nieto, a journalist specializing in the paranormal, is going through his worst professional and personal moment. After a failed suicide attempt, he comes back to life accompanied by the ghost of his mentor, Doctor Estrada, a legendary mystery communicator who died more than 20 years ago. At that moment, a virulent poltergeist case, perhaps the most important paranormal case in recent years, crosses his life.
