Sisters Anna and Rachel share a flat in Dublin, where late nights and messy mornings are the norm.

Anna is in hospital, with the Walsh family rallying around her in their own chaotic, mismatched ways.

Anna is in hospital, reeling from events of the incident and desperate for answers.

Claire has an epiphany about how to help Anna, who is weighed down by emotions she cannot release, while Luke decides to visit Rachel in rehab.

Hurt by Anna's absence, Rachel becomes even more unsettled when Claire accidentally lets something slip. Maggie receives big news of her own and later crosses paths with Luke.

The family organise an important event for Anna. Just when it feels as though everything is falling apart, a quiet moment of unity pulls the sisters back together.
