Synopsis - Vermeer's Golden Moment

I've drafted a synopsis for the Vermeer story;

1654, Dutch Republic - Delft a prosperous port and art centre. Young Jan Vermeer has just been accepted into the artists Guild, his wife Catharina is pregnant, and his friend Antonie is going to share some optical secrets that might give his art a competitive edge. Then the city is shaken by a gunpowder explosion, and before he can even reach his family, the militia Captain 'orders' him into the rescue effort. Vermeer’s a sensitive, impractical man: it's all a vivid, fascinating dream for him until he his mentor Fabritius is pulled, mortally wounded, from the wreckage. This triggers an obsession with proving his worthiness as a survivor and artist. As Vermeer tells his version of this story to Catharina, it slowly reveals his psychological and moral weaknesses, and a powerful question: why did he go with the Captain and not to those closest to him?
