George and his friends build a ramshackle tracking device for the rocket and set about testing it. Things look up for sacked security guard Shiner when he gets a job at the chocolate factory. But trouble starts when union man Huw squares up to his old rival Eric, then Shiner drops the tracker into a vat of caramel. George and his friends build a tracking device so they can establish when the rocket reaches space. To find out if the ramshackle device will work 62 miles above the earth, Shiner heads off to the coast, but Huw's aerial snaps and the rocketeers lose him after only a mile. Shiner's wife Fiona is angry because he'd promised to spend the day job-hunting after Eric sacked him from the carriage works. She blames George for their woes so he sweet-talks his Human Resources Officer Gail. She gives a delighted Shiner a job at the chocolate factory in return for George becoming her liaison officer with the staff. Eric lets the team back in the Old Carriage Works and Angela, now a singer in Ed's band, moves their rehearsals into Mission Control. But it's not long before trouble starts again. Huw, a former shop steward, can't work alongside his former boss Eric, while Shiner accidentally drops the tracker into a vat of caramel. Gail confronts George after the tracker is found and tells him to sack his mate. Shiner and Fiona have a fight, then the bailiffs appear and he disappears in George's car, saying he will kill himself. The only hope is using the tracker to find him. Can the team forget their differences to save their friend – and will the tracking system work at last? (thetvdb.com)
