Single dad George Stevenson builds a rocket to send his wife's ashes into space but he's brought down to earth when the launch ends disastrously. Though determined to try again, he is forced to realise his promise to Bethan is getting in the way of being a proper parent. Can he walk away from his dreams? After a day's work on the production line at Blossom's Chocolate Factory, George returns to his garden shed – Mission Control – convinced he can launch the rocket by moving the engine. Mary, an old colleague from the now defunct Aber Ivor Carriage Works, offers to help. Special needs teacher Pam, who is concerned about Tom's schoolwork, arrives, unimpressed by George and his mate Barney testing rockets in the back garden. George unwittingly takes Mary to an expensive Japanese restaurant, while Angela sneaks out to see Ed, a boy she fancies from school, perform with his band. Tom is left alone. The next day, Pam tells George that Tom has been missing lessons to spend time in Mission Control. The meeting goes badly. George feels he has failed his son and decides to scrap the rocket and devote himself to fatherhood. But can he walk away from his dream?
