It starts as a love song. It ends with murder.

1999

Gifty is a woman adrift in the wake of her wife's death. She's living in stasis, unable to bring herself to enter the bedroom where Helen died after a long illness. Her therapist tells her to confront her grief, but instead she wanders the streets looking for someone from her past.

Fallen nineties pop star Isobel has done everything she can to reinvent herself. Gone is the girlish make-up and provocative manner. When she lands a job working for a middle-class family, she decides to embody the perfect nanny.

Ally has always prided herself on running a successful business and being a good parent to her two children. But when her husband announces that he is leaving them to work in Indonesia for six months, and hires Isobel without consulting her, she is left angry and struggling with her chronic illness.

The women soon become tangled in a dangerous web of obsession and infatuation. Someone is going to die, the question is: who?
