ALPHA by Mike Walker
I've not actually heard anything other than a short clip-preview of this, so it's a guesstimate of the full storyline...
'Oh little Green Men and CIA Holograms and all that crap' you say, but then again you've not been around much have you ... Story of an ET computer technology that appears to threaten stability in a Religious centric future. (
as if)
"
An all-knowing computer seems to have an independent life of its own. Award-winning drama with David Calder and John Moffatt."
