Two sisters and their father have taken up summer residence in a rural mountain cottage. They receive a visit from their brother and a friend, both custom officers. During the visit the sisters go off for a brisk mountain trot. While gathering wild flowers the younger sister falls into a deep abyss. The event of her rescue is being celebrated in the homely hut, when two mountain officers bring in a long sought smuggler as captive. The two custom officials arraign their prize until two girls recognize him as the daring rescuer. The girls reveal the identity of their benefactor to the brother who, when alone, offers his charge the chances of escape only to be informed that the smuggler-hero steadfastly refuses to implicate the custom officer by escaping from his keeping. He awaits his punishment. What happens to him?
