The Château of Morbec in Brittany. A formal garden and a wide terrace with stone balustrade. In the background the château, white and peak-roofed, with great arched doors. Beyond it a distant prospect of a Breton village and of the sea beating against a dangerous coast. To the left a thick wood, to the right a perspective of garden alleys, fountains, and flowering trees. On the terrace a small table set with bread, fruit, and wine. In the angle formed by the level of the terrace and the wide stone steps leading into the garden the statue of a nymph, its high and broad pedestal draped with ivy. Scattered on the terrace and steps a litter of stones, broken cudgels, rusty and uncouth weapons. The sun shines, the trees wave in the wind, the birds sing, the flowers bloom. It is a summer morning in the year 1791.
Enter from one of the garden paths a lackey and Rémond Lalain. Lalain wears a riding dress with a tricolour cockade.
