The Secret Service - Errand of Mercy

Father Unwin falls ill from heatstroke and recovers at his vicarage. After reading a newspaper article about an epidemic in Africa, he has a surreal dream in which he and Matthew are tasked with ferrying medical supplies to Bishopsville in a flying Gabriel. When they are captured by native tribesmen for human sacrifice, Unwin must save himself and Matthew with the help of his gobbledygook.
