Planning: '3-minute-wonder'

I recently researched into the Channel 4 '3 Minute Wonder' series' and I was really interested by the format and their purpose. I have decided that I wish for my documentary extract to be from the an episode of a series. Here is the link to the series;

As there are five priorities of 'The Big Society' and the second is about volunteerism (I am planning to focus on volunteering), my documentary extract will be from the second episode of a series.
