Golden Gate: A Sedução do Poder

I bought this video because I couldn't find it streaming anywhere. I believe this was the pilot for a series but it wasn't made like a stand alone movie in case it wasn't picked up. It left so many questions unanswered. Like why was his old girlfriend acting like she has a secret (a child he didn't know about?), they would have had to have let the father die because he wasn't redeemable, his "sister" acted like she wanted to be his girlfriend. She actually said as she hugged him, "I wish you weren't my brother, you look so good!" We're they step or half siblings? Even so, that's just not normal I don't care how handsome Perry King was. They should have explained this at the beginning. Anyway, I guess I'll just have to make up my own answers.
