Stella had offered sex to a demon or whatever appeared in exchange for a much better life. It is there when Constantine makes his appearance, a demon who maintained a life outside of Hell and had a lot of money, between the two bonds that Stella believes are beginning to fall in love. However, she feels that he is hiding something from her when he disappears. Things take a turn of terror and survival when Cassiel appears in Stella's life, wanting to be part of her life and above all to protect her, why? Because Constantine is not what he claims to be and coincidences do not exist.
