All the workers at the Barcroft factory are playing the penny pools, all the more spurred on by the boss's son, Tommy, having recently won a respectable sum.

Unfortunately Tommy's father has a puritanical streak about him and will not countenance a range of hobbies and pastimes, all forms of gambling included, on company time. Renee Harland, a factory girl who Tommy has a particular soft spot for, completes her coupon diligently over her lunch break as usual, but is delayed from getting back to work by a domineering colleague; and when the senior Mr Barcroft sees her with the coupon, she's summarily sacked.

Tommy protests to his father in her favour, but it's no use: so he resigns and walks out too! Now both in need of employment, they find a quiet café for a drink and to gather their thoughts, where discussions soon escalate and Tommy decides to put his winnings to use for both their sakes.

Meanwhile, the haphazard mechanics working at a garage - Duggie, Chuck, Billy and Jack - get into a terrible confusion over a repair job and are soon also looking for new employment.
