Arriving in sub-Saharan Africa, gap year student and part-time Elvis impersonator Aidan has brought with him his principles, his broken heart and his Elvis costume. His supervisor with a Mrs. Robinson complex is Janet, who ran away to Africa 20 years ago and never ran back. And then there is Msoko, Janet's African fixer, who has her own stories to tell. What secrets are they hiding? Will they find water? Will the goat survive? And will the Rain King ever come? The Rain King asks questions about how we survive, from where the water supply is coming from, to how do we make it from sunrise to sunset each day and what gets us through.
