Anns an Ògmhios 1745, tha muinntir gleann sìtheil Thulach Neasail, Siorrachd Obar Dheathain, a’ cluinntinn na naidheachd gu bheil am Prionnsa Teàrlach Eideard Stiùbhart air tighinn gu tìr an Èirisgeigh. Feumaidh an t-uachdaran Teàrlach Gòrdanach agus am ministear Ualtar Syme, banntrach le triùir nighean, roghainn a dhèanamh. An toir iad an taic do na Seumasaich ann a bhith a’ glacadh Crùn Bhreatainn? Aig an aon àm air tìr-mòr na Roinn Eòrpa, tha Uilleam Augustus, Diùc Chumberland, a’ cumail sùil gheur air an ar-a-mach Sheumasach, mì-fhoighidneach gus am faigh e an sàs anns a’ chòmhraig. Chan fhada gus am bi saoghal nan Gòrdanach agus nan Symes air a thilgeadh bun os cionn. In June 1745, the people of peaceful Tullynessle Glen, Aberdeenshire, hear the news that Prince Charles Edward Stuart has landed on Eriskay. The laird Charles Gordon and the minister Walter Syme, a widower with three daughters, must make a decision. Will they give their support to the Jacobites in seizing the British Crown?At the same time on the European mainland, William Augustus, the Duke of Cumberland, is keeping a close eye on the Jacobite rising, impatient until he can be involved in the conflict. It won’t be long until the world of the Gordons and the Symes is thrown upside down.
