Molly and Andrew are just trying to get home to Ireland for the holidays when a freak snowstorm grounds their flight. As the snow falls over the city and over the heads of two friends who are sure they’re not meant to be together, the universe might just have a plan of its own.

Alex would like to believe she’s a woman who has it all. Or that’s what she tells everyone, including herself. But this is far from true. Actually she’s on the cusp of losing her home, her dream career as a writer is in tatters, her ex won’t speak to her, and her mother’s gone forever. But then a chance meeting with a stranger named Hope gives her the opportunity of a lifetime, when Hope jokes that perhaps Alex should take over her job in a cafe while she goes travelling.

Born into the Scottish Clan MacBain and Drumblair Castle, Liv MacBain has always dreamt of leaving the ancient homestead and becoming her own person in the world of fashion. From a young age, she worshipped the trailblazing designs of the haute couture glitterati, hoping one day to join them. With older brother Kerr, the rightful heir, Liv has been free to spread her wings. Fast forward. Liv is now 28 years old, working at a high-end fashion house and living her dream life in New York. She’s never been happier. Until everything changes with one devastating phone call from her brother.

Lara and Sonny are sworn enemies. As rival showbiz journalists, they are always out to get one-up on each other – whether being the first to scoop the latest celebrity gossip, or sabotaging a potential lead. So when their bosses ask them to join forces and go undercover at an exclusive celebrity retreat, they can’t think of anything worse – except that they are going to need to pretend to be in couples therapy to blend in.

When Liv finds herself locked in a shed with handsome stranger Ben (after they try to rescue a cat together), the instant connection they make feels like fate had a hand in it. Has Liv finally found her perfect match? But everything about the timing means there’s no way they can be together. Not least because Ben has a girlfriend and Liv is moving from London to Paris the next day. Over the coming years their paths weave in and out of each other’s lives – together, but always fleetingly. If only they could stop missing each other, who knows what fate may have in store for them.

School reunions: the perfect opportunity to catch up with old friends, dazzle old foes and basically show everyone that your life could not be going better. But for Lucas O’Rourke and Posy Edwins this isn’t quite the case. Lucas is about to lose his business unless he finds an investor fast, and Posy’s father has cut her off financially, just when she needs to get to Hawaii. And a reunion is the worst moment to come face-to-face with your rival. Ten years ago, they hated each other; what could have changed since then?

After 30 years of marriage, and a wonderful family Christmas, Louisa is stunned when husband Kip asks for a divorce on Boxing Day. He’d never seemed unhappy – and they’ve raised three children together. For months, Kip has been secretly seeing a younger woman – and if that wasn’t bad enough – it’s the woman who broke their youngest son’s heart. Now Kip is moving out and embarking on a new life with Zoe, and Louisa is left to pick up the pieces. Their beloved family home, Charity Cottage, is up for sale, and tensions are running high.

I always thought I was going to be a girl who did something. I was going to run my own business and find fame and fortune! Fall in love… But here I am. Still waiting for it all to happen, sitting on the floor, surrounded by lilies and roses, trying to do my best friend’s wedding flowers because – in her words – ‘how hard can it be, Frankie?’. The answer is actually ‘very hard’ but it’s not the only thing that’s tough right now. My boyfriend won’t commit, I barely have a job, and once again I have the hangover from hell… What I don’t know is that life’s about to throw me a curveball.

Katie Collins has barely ever left her tiny Irish village of Ennisbawn. Why would she? With its tightknit community, friendly local pub, surrounded by glistening lakes and perfectly mysterious forests, it’s a place of peaceful beauty. Or it was peaceful. Until Callum Dempsey turned up. Part of a hotshot (and, Katie has to admit, hot is annoyingly apt for him...) development team with zero eye for beauty or charm, he’s not only building a hideous hotel just outside the village, he’s also just announced a plan to knock down Ennisbawn’s only remaining pub. 

Cara and Millsy have broken up...sort of. After years of being everyone's favourite couple, always up for a party and having fun wherever they go, things have fizzled out. But when they realise they have a whole calendar of events and celebrations with friends and family coming up, Cara and Millsy can't face letting them down. So they decide to make a pact: just convince everyone they're as madly in love as ever and get through the festivities without causing suspicion, and then deal with the break up in the new year. How hard can it be...?

With her ex soon to be married, her mum back on the dating scene, and her best friend threatening to settle down with the Most Boring Man Alive, Stevie is feeling left behind. To top it off, her old uni mate Johnno West, whom she hasn't seen for years, keeps turning up as best man at Stevie's jobs. And he is looking so good. Perhaps their youthful pact—that if they were both still single in their early thirties they'd get together—is not so crazy after all? Then the enigmatic Charlie Jones walks into the frame.

Molly's a millennial home organiser about to have her first baby. Obviously her mum, Annie, will help with the childcare. Everyone else's parents are doing it. But Annie's dreams of music stardom have been on hold for thirty-five years, paused by childbirth then buried under her responsibilities as a mother, wage earner, wife, and only child of ailing parents. Finally, she can taste freedom.

Sally is a classic romantic and Harry is a classic cynic, but when a drunken bet leads the new flatmates to (badly) recreate ‘the lift’ from Dirty Dancing, and the video goes viral (#EpicRomcomReenactmentFailure), they both realise there’s potential financial benefit in blundering their way through the romcom lexicon for their suddenly vast social media following. Now, as Harry and Sally bring major romcom moments to new life – including recreating that classic diner scene – their faking it turns to making…out and suddenly they’re living a real life romcom of their own!

Years ago, Juliet left a little piece of her heart in Paris - and now, separated from her husband and with her children flying the nest, it's time to get it back!
