After another ice age, humans are compulsory underground, the survivors there, are called colonies. Sam and Briggs in Colony 7 hurry up on saving duty, when they receive a trial call from Colony 5.
Rather than watching tough survivors taking on a deadly foe, we are watching something more akin to a low achieving mouse trying to fight off a gang of militant carpet beetles.
The filmmakers' aversion to any hint of storytelling originality means that the main impression "The Colony" leaves is one of almost stupefying over-familiarity.
