Seven selected adolescents (18-25), adults (40-50) or elderly people (60-70) spend seven days together in a castle. They have never met before. The evolution of this group is a major ingredient. 7 lives has three series (I, II and III) of seven episodes each and shows what occupies them most and what they basically do not care about. The concept is based on the seven passions in life : fear, joy, anger, desire, sadness, hatred and love, all with a touch of humour and levity. As such, they let their hearts speak and reveal the deeper feelings that made them do one thing and not another. To create a filmic style, external elements were introduced: time, the castle as a living being, a black cat... All of this builds up a mysterious and uneasy atmosphere, enhancing the symbolism of the number seven.
