New Reality Series on Discovery Health Channel: What's the Name of It?

MammaHomie speaks of a new reality series on the Discovery Health Channel in which people are snatched from their homes with no notice and taken to do something they’ve always dreamed of doing (for example, walking the Ho Chi Minh Trail). Apparently it has to be done in a short amount of time (say, 72 hours) and can only be done within a very limited budget (like $3000 or something).

The website is of no help, and since I don’t know the show’s title I can’t search for it.

Anyone know what it is?
