The two main characters are a detective who is trying to find out what happened to his father and a banshee who has decided to work with the humans to maintain peace on earth.
This show it like an X-Files/Men in Black hybrid in that the two main characters are working for a governmental type organization which is regulating the alien presence on earth, but they are hiding a lot from the two main protagonists.
This show has aliens, monsters, humour, mystery, conspiracies, great characters and some great story lines.
It's a travesty that with all the TV stuff that's been release on DVD that this has missed out. There doesn't even seem to be any news of it happening any time soon either.
** Please release a DVD box set with all 40 episodes - ASAP! **
