Little Brother Little Sister, is a unique look at the coming of age and of a brother and sister trapped inside a bomb shelter all of their lives. The late teens have been raised by their "Cook" these last fifteen years since the mysterious disappearance of their parents. Cook tries to teach them manners and discipline and tries to dissuade them from their natural teenage curiosities. "Your his sister, Your his brother" says cook to which they reply "What's a sister? What's a Brother?".

The two youngsters are also realizing their own strengths both physically and of character. Although they've been warned about the dangers of the world outside they are certain something better awaits. Little Brother Little Sister explores growing up, being young and getting old in an isolation that magnifies the the true relationships between people and their need to be needed and loved. Little Brother Little Sister would be considered to be appropriate to mid to upper teen and above, with no fowl language, nudity or drug use there are a few adult references but would be on par with any PG rated movie. Little Brother Little Sister is like a combination of THE BLUE LAGOON and BLAST FROM THE PAST.
