Les mousquetaires au couvent
In Touraine under Louis XIII, Gontran and Brissac disguise themselves as priests to enter an Ursuline convent. Gontran hopes to reach Marie, who is being prepared to take the veil, while Brissac courts her sister Louise. Their plans collide with a plot to assassinate Cardinal Richelieu, and the musketeers are ultimately recognized as heroes and rewarded with permission to marry.
