Rachel (Rocky) is seemingly living her best life as the irreverent, funny beating heart of her family. Her ageing father is his unique, adorable self; daughter Willa is prone to bouts of existential angst whilst berating the fact that her mother has zero filter; husband Nick is steady, logical, sometimes infuriating.

They are messy, they are flawed, they are completely, ridiculously normal. And like most normal people, Rocky worries about what might happen next. So when a former classmate of her son Jamie dies in a seemingly random accident, Rocky becomes obsessed.

For if accidents can happen – and they do – is it truly safe to love anyone?
