The good twin Robert is dead. The bad twin Jason is alive - but burdened down by surviving Vietnam and prison. Younger brother Gibson is cloistered and overprotected. Jason wants to spend time with Gibson, and Gibby is tired of being locked up in the house, but nothing good can seemingly come from him being around his brother. It's hard to see in the preview what Jason's motives are, but it is intriguing, if not kind of bleak and depressing.
