Snowpark: The teams deal with the range of emergencies that occur in the Val Thorens snowpark, including a teenager who has concussion and a man who breaks his spine.
Insurance: Patients include Terri from Crewe, who ends up with more than 20 stitches in her shoulder, and Igor the Russian businessman, who refuses all medical assistance.
