Charly and Ellen have been best friends ever since a shared moment of transformational theatre in Year Eight Drama Club.

Ten years on, Charly is leaving New York and a dubious career leafleting in Broadway, to visit Ellen back in their home village of Cumwell. Neither of them can wait to relive the glory days of their friendship: a non-stop rom-com of hair crimping, MmmBop and an unhealthy level of co-dependence.

But Ellen soon discovers that Charly isn't planning on moving back permanently, crushing the dream they'd always shared of living in London together. Now at odds and no longer as inseparable as they'd imagined, Charly discovers that her mysterious lack of periods is a result of something much bigger and scarier. Their world is suddenly tipped upside down as they fight to make sure their friendship rom-com has a happy ending.
