Jamie finds himself between a rock and a hard place when a redcoat deserter from his past resurfaces. Claire tends to a laboring Jenny while Jamie and Ian join The Watch, resulting in devastating consequences. - Whilst Jamie has been gone, sister Jenny and her husband Ian have been paying a gang of ex-militia/highwaymen protection money, food and good tobacco to keep them from the jaws of the Red Coats. Tension is high as Jamie has to assume a 'cousin' of the family so as to hide the fact that he has a price on his head. Unfortunately, someone they have come across recently connects up with the gang - and he knows Jaime and his secret. This rogue has a plan for the gang to rob a rent packet but he also blackmails Jaime to keep his secret - or has he spilled the tale already. Jenny and Claire are busy bringing the latest Fraser into the world - a breech birth.
In prison, Jamie discovers that an old foe has become the warden – and now has the power to make his life a living hell. Over the years, Claire and Frank both put their best foot forward to share a harmonious marriage, but an uninvited guest shatters this illusion, bringing their differences to light.
