When Nénette discovers the identity of her father in a letter, she quickly goes off in search of him. But instead of finding her father, she is met by her half-brother, Paul. Paul, a bitter man who gave up his dream to take over his father’s pharmacy business, is less than thrilled at the arrival of his ‘embarrassing’ half-sister. After refusing to take her in, he soon gets a taste of his own medicine. Under the influence of a potent drug, for one day Paul is generous, happy and sensitive. The next morning, however, once the drug has worn off, his nasty side comes back...
