The four-part series follows mother Joanna (Coleman) coming to terms with the tragedy alongside husband Alistair (Top of the Lake’s Ewen Leslie) as her psychological state disintegrates in the glare of public scrutiny.
According to the BBC, the catastrophe is a “catalyst for a journey into the disintegrating psychology of a young woman, exposing the myths and truths of motherhood.”
As we see in the trailer, Coleman’s character is subjected to gruelling TV and police interviews before attempting to run in front of a speeding lorry.
The drama – adapted by Jacquelin Perske from the popular 2013 novel of the same name by Helen FitzGerald – will also star Asher Keddie, Stella Gonet, Sophie Kennedy Clark, Alex Dimitriades, Markella Kavenagh and Shareena Clanton.
