Boomers follows the ups and downs of three couples living in Thurnemouth, 'Norfolk's only west-facing resort'.
There's Alan and Joyce, who are coming at retirement from very different directions; Alan wants to slow down, Joyce wants to speed up. Alan tries to avoid as many of Joyce's social commitments as possible, but downsizing to a bungalow has meant there are fewer places for him to hide.
John and Maureen, living in their gadget-filled dream house, are adventurous in every aspect of life including the bedroom. For them, 60 is the new 40. However, there's a reminder of what's around the corner with Maureen's ever-present mum Joan.
And finally there's Trevor and Carol, who've got non-communication down to such a fine art that if Carol spent a weekend away, Trevor might not even notice.
Thirty years of living in each other's pockets have shown the benefits and drawbacks of the group staying friends.
Alan is looking forward to Jean's funeral; his old mate Mick, Jean's ex, is coming over from Spain especially for it. Alan's wife Joyce isn't so happy - Mick has always been a bad influence. John's not happy either - he's been convinced that Mick has a thing for Maureen ever since a notorious holiday in Weymouth. And when Mick turns up, he's got a surprise for everyone - a 30-year-old Lithuanian wife who seems to understand Trevor more than his wife Carol ever has.
