Sydney Bristow is a college student who has an unusual job she is a spy working for the CIA under secret conditions where not even her friends knows what she does. When she gets wasted at a party and boasts about her cool job, all her friends are killed by her employers and Sydney discovers that maybe she isn't working for the Government's intelligence community. Indeed she has actually been working for SD6, an agency that is actually a shadowy criminal organisation world-wide. Sydney joins the real CIA and works as a double agent to help CIA Agent Vaughn to bring down SD6.
As others have said, it helps to be maybe not an Alias "fan" but certainly you need to have seen a handful of episodes of the series to get the aspects of Alias that this spoof effortlessly goes at. With a plot that mimics the early seasons of Alias, this is a little bit like kicking a puppy and is why I think that being a die-hard "fan" might prevent you enjoying it because, while some spoofs are affectionate, this does rather ring of joyful mocking. And I have no problem with that because, while I enjoyed it sort of for several seasons, it deserves it for taking itself quite as seriously as it did. Having a man play Sydney is probably a bit harsh but it does work as a joke although not one I suspect Jennifer Garner will appreciate.
The material is sharp and it shows the writers are very aware of the show and how it works OK they have a massive, easy target but they still deserve praise for getting the bullseye. The slight downside of it is that some of the material is too obvious and lets laziness creep in, but I did appreciate the more imaginative touches, for instance what they did with Francie. As Sydney Rankin is funny but can't bring the easy pratfalls to life in the way I would have liked. Others, freed from carrying the short have simpler tasks and get short bursts of hitting their target and they do so as well as the material does.
Not brilliant then but for those able to laugh at the show it is certainly worth a look because it is bang on and, while not razor sharp, is consistently amusing by taking the p1ss out of a show that rarely seemed able to take itself anything less than 100% seriously.
