You might want to start with the general concept of how algorithms work, what a computer program does, code being a set of instructions that is read by another computer program, flowcharts, and the like.

It depends on how much time you have. If you are only meeting them one day for a few hours, give them a page of code that does something and run through how it works from start to bottom, then give them the basic control and data structures like loops and lists and a simple goal like a blackjack program or number guessing game. You may also want to make (or find online) a cheat sheet of the language keywords and what they do, and hand a copy to everybody.
