A Royal Affair is a gripping tale of brave idealists who risk everything in their pursuit of freedom for the people, but above all it is the story of a passionate and forbidden romance that changed an entire nation. A young queen (Alicia Vikander), who is married to an insane king (Mikkel Boe Folsgaard), falls secretly in love with his physician (Mads Mikkelsen) - and together they start a revolution that changes a nation forever.
