actually the bromine at the benzyllic position gets replaced by the nucleophile :PhS^-.....the most important part of the reaction is that nucleophilic substitution of the halide atom can occur only at the alkyl region.....that is why we are replacing the bromine and not the fluorine atom that is linked to the benzene ring by strong partial double bond !!!!
