The Griffins and the Gallos have been battling for control of Chicago's underworld for generations.
Their bitter rivalry reignites when Aida, the youngest and wildest Gallo sibling, crashes a party at the Griffin mansion, accidentally setting fire to the library.
To stave off all-out war, her father arranges a marriage with Callum Griffin, eldest son and heir.
Cold, ambitious, and brutal, Callum is determined to tame his headstrong bride. Aida is more than capable of giving as good as she gets - starting with poisoning Callum on their wedding night.
