NBC have released the first synopsis for the final episode of Constantine , and it sounds like it will be a big one as we finally learn the truth behind the Rising Darkness and Detective Jim Corrigan (Emmett Scanlan), a.k.a. The Spectre, returns. Check it out!

A YOUNG GIRL’S ABDUCTION REUNITES JOHN AND JIM CORRIGAN – EMMETT SCANLAN AND MICHAEL JAMES SHAW RETURN – John (Matt Ryan) and Zed (Angélica Celaya) return to New Orleans when Detective Jim Corrigan (guest star Emmett Scanlan) asks for their help in the case of a missing girl. Papa Midnite (guest star Michael James Shaw) takes steps toward exacting his revenge on John. Meanwhile, the truth behind the Rising Darkness comes to light. Harold Perrineau also stars.

It's more than a little depressing to think that this might just be the last ever episode of Constantine, but even a new time slot doesn't seem to have done the NBC series that much good. Of course, it was doomed for a start in some ways, but here's hoping a miracle happens and we end up getting a second season...anyway, what do you guys think about this official description?
