Alexia's haircut after she cut her hair by herself and when she is picked up by the Captain.
At 3': the snail-shaped scar is not accurate as craniotomies are prepared with a semi-circular scalp incision.
The captain tells Rayane that they need to intubate the non-reactive patient on the bed but actually uses a Laryngeal Mask Airway (LMA), which is not considered an intubation (orotracheal or nasotracheal procedure).
At 1:20'50: the dad pushes Adrien's hand which sends the syringe to the side; there is no needle attached to it.
When Alexia is inside the car having sex with it, she is supposed to be fully nude, but at one point you can see a flash of material of the shorts or pants she's wearing.
With time, hair grows back over the shaven part of the scalp with only the scarred tissue appearing hairless: Alexia's hairless patch on the side of her head is way too big.
At 6: the female protagonist puts on lipstick by looking in a car side-mirror but she is really looking towards the camera or the viewer could not see her lips.
The dad should have made an appointment with a maxillofacial surgeon to fix his son's nose after a week or so (judging by the fading hematomas under Adrien's eyes, it is understood that much time has passed).
On their way to the hospital in the Fire Brigade ambulance vehicle, a junior staff would be the one driving, not the captain would has more medical experience and is required at the back.
The captain should have asked Rayane to start chest compression and apply a defibrillator on the unconscious patient on the bed. They never start CPR (cardiac and pulmonary resuscitation) but only perform ventilation.
The captain should have rolled on his tummy straight away when the front part of his shirt started catching fire instead of reaching for a cloth.
When the mother of the unconscious man drops to the floor, the captain asks Adrien to perform mouth to mouth ventilation; he should have provided Adrien with a mask and a bag to perform Bag-Valve-Mask ventilation which is safer and more effective.
On their way to the hospital in the Fire Brigade ambulance vehicle, Rayane should not have been looking at his mobile phone but rather monitoring the patient.
