I am not sure what you should plea.
All legal matters are facts based. It depends on what happened during that hour. Let's say you were abducted by bad guys for ransom and freed yourself after 1 hour and arriaved at home, you would plea "not guilty." On the other hand, if you were meeting your secret lover in your neighbourhood while your hu*****and was at work, you would plea "guilty."
This is a big world, don't assume we all know the facts. As a lawyer, the first lesson I learned in practicign law is --- assume nothing.
I am not making fun of you. I am just saying that if you want people to be able to give you useful advice, lay out the facts.
