Mr Bigstuff season two airs on Sky and NOW and the second outing picks up just weeks after the bombshell news that the brothers' dad's not actually dead.
Lee Campbell (played by Danny Dyer) and his brother Glen (Ryan Sampson) have handled the news very differently, but find a way to unite as they attempt to track their father down.
Another fan-favourite returning for the second season is Kirsty (Harriet Webb), who is "taking charge in the bedroom and the boardroom".
Other returning stars include Adrian Scarborough as Ian, Fatiha El-Ghorri as Aysha, Victoria Alcock as Sue, Ned Dennehy as Bunny and Clive Russell as Uncle Ron.
Here is all you need to know about the new guest stars for season two, which was created and written by Sampson.

Rita appears in episode two and she is described as an eccentric and flirtatious woman the brothers believe is connected to their missing dad, Don Campbell.
Rula Lenska is a 77-year-old English actress known for her film roles in Queen Kong and Aura.
On TV, she is remembered for playing Claudia Colby in the ITV soap Coronation Street.
Pam - Linda HenryPam is described as a no-nonsense, hands-on mechanic at the family haulage firm.
Linda Henry reunited with her EastEnders co-star Dyer for this project, with the pair having shared many dramatic scenes on the soap over the years as Mick and Shirley Carter.
Most notably a storyline that revealed Mick and Shirley were not siblings as first thought, but that he was in fact her son.
Henry is a 65-year-old English actress who also starred as Yvonne Atkins in the ITV prison drama series Bad Girls.
In episode five, Shaun Williamson stars as a furious children's entertainer who finds himself at the centre of another brotherly showdown.
Williamson is another EastEnders alumnus, having played Barry Evans - a role that would go on to define him.
He later starred as a satirical version of himself in the BBC/HBO sitcom Extras.
After leaving the soap, he starred in Sexy Murder, Life's Too Short and Al Murray's Great British Pub Quiz.
