Survival of the imminent holocaust, Joe believes, demands positive action. Begging an old tobacco tin from a neighbor, he sets about filling it with everything he thinks he'll need to make it through the dark days of nuclear winter ahead.

Meet Joe, aged 33, struggling to survive a very different bombshell. He's got Helen, the wife he doesn't live with any more; Georgie, the little daughter he hardly sees; a job he can't stand... and an old tobacco tin lurking in the bottom of his wardrobe sealed against a future unknown. He's prepared to force open the tin, but how could anything inside save him from the fall-out from his nuclear family?
