Aidan Bloom, a struggling actor, father and husband, is 35 years old and still trying to find a purpose for his life. He and his wife are barely getting by financially and Aidan passes his time by fantasizing about being the great futuristic Space-Knight he'd always dreamed he'd be as a little kid. When his ailing father can no longer afford to pay for private school for his two kids and the only available public school is on its last legs, Aidan reluctantly agrees to attempt to home-school them. Through teaching them about life his way, Aidan gradually discovers some of the parts of himself he couldn't find.
