It's August 2007. Lauren Marks is a 27-year-old actor and a PhD student, spending the month directing a play at the Edinburgh Fringe Festival. She's in a bar, standing onstage, performing a karaoke duet of 'Total Eclipse of the Heart'... and then a blood vessel in her brain bursts. When she wakes up in hospital, days later, she has no internal monologue, and a vocabulary of only forty words.
