My Wife's Personal Trainer

The premise

Danny is short of money when a billionaire hires him at $5,000 a week to train his wife. The catch is that the husband designs the programme, and each new instruction he hands over in a sealed envelope takes the sessions a step further. Meanwhile Danny's girlfriend is beginning to wonder what the job really involves.

How it is built

Five episodes suits one escalating situation, and the brief builds the escalation into its mechanics: each instruction raises the stakes a notch. Two episodes are free; the remaining three cost 12 tokens each, 36 altogether.

Who it is for
