People go missing all the time but it's not usually government-funded.
Four young adults go missing and find themselves in the complex world of 'The Farm'. On a news board outside the farmhouse is a growing list of rules and four dates circled in red on the calendar each a week apart.
Rule Number One: Stick with your pair.
Rule Number Two: No talk of the outside world
Rule Number Three: No attempts to Leave the Farm.

March 1st
March 8th
March 15th
March 22rd

Why are they in 'The Farm'? Where is the Farm?
