When Patrick Sheppard suddenly and tragically dies, he leaves behind a family in pieces. Zoe has lost the love of her life. Ethan, Gabe and Beatrice have lost their larger-than-life dad. There's a hole where Patrick should be and none of them can see a way forward.
For Patrick's brother Dan, though: his mission is clear. He needs to help the Sheppards to find some sort of happy again and he makes a promise to himself to try and come close to the man Patrick was. But as he immerses himself in the frantic school run, dishing up tea and sorting the bills, Dan begins to see he might not have known the man Patrick really was, underneath it all. His brother was keeping secrets.
Juggling his heartbroken family and the catastrophic truth that could break them all over again, Dan has to face what he's been keeping from himself all this time: what really happened on the night that Patrick died.
