Inferno is the second part in the "Three Mothers" trilogy, the third has yet to be written. A woman (Irene Miracle), seeking out information on the "Three Mothers", is in New York to find the Mother of Darkness. Miracle looks for the second key, which is hidden in a cellar, and finds herself submerged in some rooms underwater in a nicely shot sequence. She sends a letter to her brother (Leigh McCloskey) who is in Rome studing music. A friend (Eleonora Giorgi) finds the letter and after reading it goes to a library to find a book on the Three Mothers. She is murdered later that night. McCloskey gets the letter back and talks to his sister on the phone. Miracle asks him to come to New York, and he does. While looking for his sister he finds the Mother of Darkness. The music in Inferno is by Keith Emerson, of Emerson Lake and Palmer, and is almost as pounding as Suspiria.
