Meet Vincent Swan, double glazing salesman extraordinaire. His team include Fitzpatrick, a charmless reprobate, and Lavender, a failed musician. The team bet on whether Fitzpatrick can pull off the ultimate salesman's con, and Vincent's attempt to convince an old colleague to join the double glazing business takes an unexpected turn.
Vincent, Fitzpatrick and Lavender meet a group of men from a local publishing company, raising the alpha male stakes when the trio discover the exciting perks the publishers receive in their line of business, namely company cars. In the showroom, receptionist Carol tries to get to grips with the new office computer. Elsewhere, in a bid to save face, Fitzpatrick puts faith in his comprehensive knowledge of the company Cachet's home turf, with potentially dangerous consequences for everyone concerned.
When Vincent receives a visit from a tax inspector, pursuing him for unpaid tax, he decides that now would be a good time to get out of the showroom and spend more time with his family.
When Vincent and Lavender discover that Fitzpatrick is a CB radio enthusiast, they can't resist going undercover to dupe him.
Vincent's life has taken a turn for the worse - kicked out of the family home, in debt to the Inland Revenue to the tune of £50k, and worst of all - he's lost his sales mojo. He's gently sliding into the abyss when absolution appears in the most dangerous of forms.
In a bid to get back everything he's lost - his marriage, his livelihood, his self-worth - Vincent concocts a spectacular plot to return to his rightful place.
