In 2015, the bishop of Aberdeen wrote to the bishop of Aba in Nigeria with an urgent request – do you have any spare priests? Father Maximilian Nwosu and Father James Anyaegbu are the answer: two Nigerians sent on a mission to serve the Scottish Highlands.

Based in Inverness-shire, they drive relentlessly from one remote church to another trying to keep a feeling of community alive. Will their good humour and Igbo songs make a difference?
