Cecilia discovers an old envelope in the attic.

Written in her husband John-Paul's hand, it says: 'to be opened only in the event of my death'.

Curious, she opens it - and time stops.

John-Paul's letter confesses to a terrible mistake which, if revealed, would wreck their family as well as the lives of others . . .

Cecilia wants to do the right thing, but right for who?

If she protects her family by staying silent, the truth will worm through her heart. But if she reveals her husband's secret, she will hurt those she loves most . . .
