999: On the Front Line

A woman collapses on a narrowboat, showing signs of a stroke. She's confused and keeps repeating herself, which is out of character. An ambulance is called to a woman who has collapsed, but while she is being treated, she falls to the floor again. A daughter is concerned for her mother, who has terrible pain in her face, and a woman who hasn't eaten for two days is weak with a very swollen stomach and needs to go to hospital.
