Allison and Deacon are desperate for a baby, but they've run out of money to fund any more IVF treatment. So they decide to 'borrow' the £50,000 they need from their rich boss Alfie, who they discover is illegally creaming off money from the company.

Allison starts IVF and pressure mounts to turn the stolen bitcoin into usable money, so Deacon asks his creepy uncle to help launder it. Meanwhile, HMRC launches an investigation.

Kethan wants Deacon to carry out a job for him that involves a bag swap in the Channel Islands, while Alfie struggles to convince HMRC that everything is in order.

Deacon and Allison are dragged deeper into the criminal underworld when they steal a Ferrari to pay their blackmailer's demands. Can they fence a car, get HMRC off their backs, and make it to the IVF clinic for 5?

Deacon and Allison make an enemy of Kethan and commit to a life on the run. As Esme and Alfie both grow suspicious of their behaviour, Allison takes the pregnancy test that will reveal if it's all been for nothing.

Esme helps Deacon and Allison make their escape after Kethan and Alfie join forces to catch them. Will they get away? Will their relationship survive? What is Allison about to reveal that changes everything?
