Jess takes her 10-month-old daughter Betsy to the hospital after Ed wakes her up, telling her something is wrong with Betsy. Ed is too drunk to drive, so Jess goes alone, panicked and unsure of what caused Betsy's condition, which is later revealed to be a skull fracture.

Liz, who works as an A&E doctor and is also Jess's close friend, becomes suspicious of Jess because Jess cannot explain how Betsy got the skull fracture. Despite their friendship, Liz makes the difficult decision to call social services due to the unexplained nature of the injury.

Jess is portrayed as being in a state of panic and confusion. She struggles with serious mental health issues following her third pregnancy and is uncertain about how Betsy was injured, which adds to her distress and self-judgment about her capabilities as a mother.

The hospital, Thames Bank Hospital, is where Betsy is admitted to the ICU and where Liz works. It serves as the critical setting for the unfolding drama, including the medical examination of Betsy's injury and the social services intervention initiated by Liz.

Ed wakes Jess up to alert her that something is wrong with Betsy but admits he is too drunk to drive her to the hospital. His intoxication and inability to assist contribute to Jess's isolation and panic as she takes Betsy to the hospital alone.
