It's the 1980s.
Coral O'Malley is discovering feminism, pacifism and Duran Duran.
She's a chip off the old block of her beloved dad, Gerry. Only he's fighting a battle of his own with the British government over that time they dropped a nuclear bomb on him. And then there's the small matter of the school public speaking competition...
Present day and the eve of Gerry’s funeral. Coral's aunty Maureen has been doing some grief-induced clearing out and hands Coral the old diaries she’d thrown out long before. Only Gerry had fished them out of the bin again. Coral is transported back to the 1980s, a young girl growing up with her dad, Gerry – a damaged man who has suffered as a result of his service at the British H-bomb weapons tests in the 1950s.
An industrial-scale injustice that overshadows their family, and the lives of thousands of families like theirs. Gerry is fighting the British government for justice. Only Gerry helped make the nuclear bomb and Coral’s Ban The Bomb. There will be an explosion.
