During the night, Roubier is exhausted by his two talkative passengers, and misses a right turn, and is precipitated in the void after the woman's dog landed on the accelerator.

At night time, Roubier turns on his portable television and succeeds into accessing the Daily Bulletin Programme, who exaggerates the disappearance of the rich industrialist, to the amusement of his two passengers.

At one point, the woman undresses her shirt with the intention of tanning, which gives Roubier the idea of taking out all of the clothes available in the car, and tying them together to form a rope, in which the passengers could descend, and attain safer grounds.

The bottle eventually lands in a café in Saint-Tropez, where the message is received by a couple, who involuntarily alert the police, who quickly rush to the right turn Roubier had missed, where they find the car intact, amazed at this queer sight.

The rescue operation begins immediately, but quickly goes wrong, after the woman's (whose name is Mrs Muller) husband attempts to destroy the rope sent down to recover the occupants of the car, livid with jealousy at the sight of his wife and the hitchhiker hugging each other.
