It is a series of action and drama that tells of a dangerous adventure by the group of prisoners and guards in 1963. In that bad period, all prisoners and guards disappear in mysterious circumstances from Alcatraz, where they no longer have a full impact on everyone. Nowadays, they are re-emerging as a secret agency is trying a new mission to re-arrest them.
Happily, there are reasons to watch Alcatraz, starting with an appealing cast and a premise that really does not require a college degree in the mythology of other worlds.
The overarching storyline is filled with enough of the supernatural to hold the attention of those who prefer their cast threatened by the occasional smoke monster.
