My family is trying to remember a movie about 2 kids that are livinging in a compound of sorts and are forbidden to leave due to possible disease and death on the outside. It's a ploy to keep the kids from leaving. These 2 kids are determined to find their parents. We think it's set in a futuristic time. Not a lot to go on. We've been racking our brains trying to figure it out. Please help!!

Maybe Logan's Run, or Soylent Green?
