Fiancial Advice for someone who is in big trouble. What should my friend do?

My friend's parents are in debt 2 Million dollars because of some bad investments. They are trying to pay the mortgage on their home. The mortgage is 10k per month. The husband just lost his job and the wife doesn't make enough to cover the mortgage. What are their options? They are asking my friend to give them $2,500 a month for an indefinite amount of time. I told her to tell them to file bankruptcy. What do you think? Please help.
