For the Goodman family, Friday Night Dinner is just like Sunday lunch: just take two days away, change the meal to dinner, and you’ve pretty much got it. Adam and his brother, Jonny, view Friday night dinner as a necessary annoyance - necessary because they get fed, and annoying because, well, they have to spend the evening with mum and dad.
Mum and dad are having a clear-out, and they’ve enlisted their son’s help. As they settle down for the first family meal of the season mum’s happy to have everyone together, but then things go downhill: their neighbour Jim keeps interrupting because he wants to use their toilet and an eBay bidder turns up to pick up their sofabed.
When Adam and Jonny come home to find Dad secretly peering into his underpants with a magnifying glass, they're desperate to find out what he's looking at.
Meanwhile, Mum is just trying to have a nice Friday night, but Jim - the neighbour who's terrified of his own dog - keeps interrupting the meal.
Dad takes Adam - who's single - into the toilet to have a private chat about 'females'. Soon the whole family are in the loo quizzing poor Adam. Jonny is loving it.
And finally, the secret behind Dad's pants-peering is revealed.
Mum's excited about the new curtains, but the boys and Grandma think they're horrible. Mum is annoyed.
Meanwhile, Dad drops Mum's beef casserole all over the kitchen floor. It looks disgusting. Dad scoops it back into the dish. The boys are not happy about their meal.
Later, the argument about the curtains spreads, and Jonny leaves in a huff to go to the pub. Adam joins him.
At home, Mum and Grandma are still not talking, so it rests with Adam to resolve the family argument. But can Adam save the day?
When Mum finds out that Dad didn't throw away his old boxes of science magazines in their clear-out, she goes mad. So Dad builds a bonfire and promises he'll burn them all. But Dad is only pretending to burn them, instead squirrelling the boxes off to his shed in the garden.
Mum is excited as her best friend, Val, is popping around with her new dress for her daughter Karen's wedding. Adam and Jonny are convinced Karen has a face like a foot. Meanwhile Jim's dog, Wilson, goes missing, leaving Jim distraught.
Later, Val comes round. She looks just like Mum: similar hair, similar clothes and - according to Dad - "similar bottoms". She tries on her dress. The men are instantly bored.
Will Jim ever find Wilson, and will Mum venture once again into Dad's shed to discover the truth behind his "pretend bonfire"?
It's Adam's birthday. As he arrives home, a silver Mercedes almost runs him over. Inside is Sheila Bloom - or 'Bitchface' as Adam and his family call her. 'Bitchface' is famously obsessed with her Mercedes, and after some catty remarks about Adam's 'Yugo' ('Err... it's a Nissan'), she speeds off.
Dad reveals that he used to have a thing with Bitchface years ago. The boys can't believe it. Mum's not happy.
Later, the family abandon dinner and go for a Chinese, but Bitchface is there. An awkward chat ensues, and finally Dad reveals exactly what he got up to with her...
Adam comes home to find the house looking immaculate, with classical music playing in the living room, Mum's posh bowls on the dinner table, Dad in a smart suit, and - most mysteriously - the table set for five.
The doorbell rings and in comes Tanya Green, a girl Mum has been trying to fix up with Adam for months. What follows is possibly the most excruciating family dinner scene of all time.
Meanwhile, Jim has been locked out as his dog, Wilson, has swallowed his keys. Inside, the blind date continues, but will Mum's dream of an Adam and Tanya wedding come true?
