Caroline arrives in London to celebrate her boyfriend Kash's 30th birthday, only to realise that his lack of respect for her will not change. Kash meanwhile is wrestling with the knowledge that whilst he is a 'soul shifter' and can steal other people's bodies, after his 30th birthday he can no longer soul-shift and he will be in the same body forever. The tension between them builds and Kash makes an impulsive soul-swap in order to keep Caroline's interest - but can he hold his jealousy in check, and will Caroline finally see what has been happening?
