When a young postman, suspecting his older girlfriend of infidelity, follows the man he fears is her lover around Paris, he finds himself joined in his investigations by a schoolgirl bemused by the intrigue… The first film in Rohmer’s second series – about the amorous desires, doubts and dilemmas of young people – is a beautifully bittersweet fable about the importance of trust and our blindness to the needs of others.
