What would it take for a woman to walk away from her family?

Greg and Marie have been married for 19 years and have three children aged 17, 14 and five.

As this drama begins it’s nine months after mum Marie (Paula Malcomson) suddenly walked out saying she was ‘drowning’.

The first episode is told from the perspective of Greg (Christopher Eccleston), a hardworking dad who is completely at a loss as to why his wife has left.

The children are devastated, but still Marie won’t come home.

What has happened to make her take such drastic action?

The emotional story, filmed and set in Belfast, plays out over three episodes as this gutsy drama explores the taboo of a mother leaving her children.
