This could be the strangest love story you'll ever see.
A high flying London banker falling head over heels for a convicted drug mule serving life in a Bali prison.
She is Nikki Butler, a mother of two, and wealthy finance worker.
He is Scott Rush, one of the infamous Bali Nine drug couriers.
They’re in love. In fact, they’re engaged.
Scott proposed in his cell. Nikki said yes.
It sounds completely ridiculous — but it's true.
