On Monday night, the Nine Network will cross a line and how they come back from it with any sense of dignity that remains after the 60 Minutes debacle is a mystery.

Television networks are renowned for doing anything to get viewers' eyes on the box, but Nine's new observational documentary The Briefcase is a vile and despicable grab for viewers that network bosses should hang their heads in shame over.

The premise of the series is that two families who are in dire financial need find on their doorsteps a briefcase containing $100,000.

They must decide whether to keep the whole lot, keep some and give some to the other family, or give the other family the lot.
