Daisy and Drew are life coaches. It may be an unrealistic-sounding profession, but they find themselves in heavy demand as human existence becomes more complicated. Whatever your issue, they can help - maybe.

Life coaching has been one of the growth industries of the past 20 years, spreading rapidly in the internet age. Since we have yoga coaching, swimming coaching, and probably coach-driving coaching, it's easy to see why someone would be drawn to the idea of a coach to guide them through the very business of an increasingly complicated existence.

But what sort of people would offer themselves up as experts on life itself?

Drew and Daisy are two of these people. Together they run one of the country's most successful coaching firms - except 'together' isn't really the word. Daisy, who founded the company, is methodical and academic. Drew on the other hand wings it all the time, counselling clients by text message or conducting appointments at the gym while semi-naked. The trouble for Daisy is that Drew's approach works.

The tension between the two - not helped by the interjections of useless assistant Malcolm - has been growing for a long time. But it's a bit late to go their separate ways now... a lot of people are depending on them.
