Il était une seconde fois - Season 1

Vincent, in his thirties, dreams of winning his ex, Louise, again. He's grief-stricken and driven to despair, kisses the break-up goodbye by nocturnal parties, ephemeral affairs - until this day when a delivery man gives him a parcel he has never ordered. A strange box, without any bottom, through which he would experience a time travel which brings him back - at Louise's side before they split up.
