Open to women. There doesn't seem to be a cash prize, just that a winning project might get to be in development for a year? Who knows. It may be of interest to those writing a TV series.

Application and contest website:

There's also something for an independent pilot -- that doesn't seem to be women-only. Check out the "Submissions" tab on the link provided to see other contests. Again, this doesn't appear to be that well known, so who knows?
