The End We Start FromThe End We Start From

A woman gives birth as London floods and, with her husband and baby, flees through a crisis-hit Britain in search of safety.

Protracted storms and heavy rain flood low-lying parts of London just as a woman, played by Jodie Comer, goes into labour. She gives birth to a son, Zeb. With the flooding spreading across Britain and supplies and shelter growing scarce, the woman and her husband, R (Joel Fry), leave the city with their baby. They head north through a country that has become dangerous, looking for safety and somewhere to stay. Their first refuge is the home of R's parents in the countryside, where they find that the situation is also catastrophic.
