I hope it helps you, from veteran to lone ranger?
The film is adapted from the memoirs of Jacques Myslin. It can be said that the director's loyalty to the original work has reached the point of following suit, and even there are some traditions in structure. The standard process of biographical films basically does not use those fancy montages that are popular now, except that the beginning of the last episode of Death Instinct took a few minutes to flash back, and the narrative development behind it was completely in accordance with the protagonist's life trajectory. Because only in this way, the audience will think from the perspective of civilians, how can a handsome veteran become a thief step by step, run rampant all over the world, leave repeated crimes on two continents, and finally die tragically at the muzzle of the Paris special police.
