All debts must be paid. In blood.

When underworld loan shark Davie Saunders is gunned down at his daughter's wedding, his loved ones are sure that a rival East End crime family is responsible. Davie's widow and daughters must now step up and take control of Davie's empire, but from the beginning it's clear they're in way over their heads.

Shy bride Mia has no experience of giving orders, self-centred middle-child Kelsey is more concerned with keeping her affair with bodyguard Todd a secret, and baby of the family Scarlett is very firmly kept out of the business while she finishes her education.

But all three sisters, as well as ex-model mum Amanda, are determined to do whatever it takes to get what they're owed.
