Ben Jewell and his wife Emma have just learned that their ten-year-old autistic son Jonah, aka JJ, has been rejected for a residential placement because the local authority has decided that he would be better served at home. To help their case, Ben and Emma decide to temporarily split up, because single dads in their situation have a higher success rate with tribunals. Emma will stay at the family home, and Ben and Jonah will move in with Ben's cantankerous father Georg, who has always been distant towards Ben, but dotes on Jonah.

- Dream Sequence: Ben has a number of these, many involving airplanes or airports.
- Drowning My Sorrows: Georg takes Jonah for a walk as soon as he and Ben arrive. Once they're out of the house, Ben gets smashed and falls asleep in front of the TV to cope with the prospect of not seeing Emma again for the next few weeks.

- Grandparent Favoritism: Ben doesn't understand why Georg is so much more open and affectionate with Jonah than he ever was with him.

He found the town completely empty and smouldering in places, with the windows smashed, and when he tried breaking into houses to look for food, he found cartridge cases littering the floors and the mouldy remains of one hastily abandoned meal. He arrived at the sanitorium just on time to hear the Nazis gun down the nurses for killing the patients. He realized what happened when he found Jonatan's body.
- Liquid Courage: Ben has been drinking to deal with fear since he was nine.
- Mean Boss: Before Jonah was born, Ben had an abusive boss who delighted in humiliating his employees. Once he subjected Ben to a pseudo-kidnapping and ordered him to clean up more than a hundred empty bottles from his car and carry them to the skip in full view of coworkers, then ordered him to confess to being an alcoholic, go to Alcoholics Anonymous, and provide proof that he went. Realizing that his boss wanted the ego boost of "saving" Ben from alcoholism, he quit his job and got drunk as soon as possible out of spite.
- Meaningful Rename: Georg Jewell was born Georg Friedman, but changed it after his family died in The Holocaust. He picked his new name from two sources: "Jonatan's Jewel," his brother's beloved piece of glass, and the Jewelly Sanatorium for Autistic Children, in which Jonatan spent his final months.Georg: I was somebody else, so I should change my name and what else could it be?

- Even though Jonah wears nappies, he's so prone to these that Ben receives a plastic bag of soiled clothing at the end of every school day.
- Georg urinates on Ben while he carries him to the bathroom because his cancer and radiation therapy have left him too weak to walk to the bathroom himself.
- The Reveal: A child's home situation has little or no impact on success with tribunals. Emma just made that up so she could get away from Ben and Jonah. She was sick of Ben's anger, self-pity, and drinking, and exhausted from taking on all aspects of Jonah's care that required thinking ahead.

Jonatan was very attached to it, and was allowed to bring it with him when he was institutionalized. He still had it when Georg found his body. Georg couldn't bring himself to bury it with him, so he took it to England as the only thing left of his family. Decades later, he passes it on to Jonah, who brings it with him when he is institutionalized.
- Unexpectedly Abandoned: As a child, Georg came home from wandering the streets of Budapest to an empty house. His parents had been taken by the Nazis.
