Alias gives the word "undercover" a whole other meaning — as in the extreme lack of cover. Based on the television series starring Jennifer Garner as Sydney Bristow, you are disguised in ridiculously conspicuous outfits peaking around corners and hiding behind glass dividers as if transparent walls make good hiding places. Apparently, CIA agents are unable to see through glass, and sneaking into empty rooms with sliding glass doors requires extra precaution. Ahh, Acclaim. How we miss your unique brand of mediocrity.
