Asha works is a nurse at the ER. She takes a call from her parents who are sad she isn't home on Christmas. But she explains that after years of avoiding this shift, her luck ran out. 
We then meet Jake who is a reporter covering the Christmas Day basketball game. He's leaving the game and sees a women with a bunch of gifts in her hands and goes to help her. He ends up slipping on the ice and goes to the ER. 
When Asha sees him, it's clear they knew each other. She was his chemistry tutor in high school and he was a mr. athletic in high school. They catch up on where they've been. The sparks begin to fly and his heart rate begins to increase. HE shoots his shot and asks her to go out for a drink and she says yes! 
They have some candy cane martinis, talk about their parents, and he walks her home and he's about to walk away but then he pulls her in and they kiss!!!
We then see a year go by and see them grow closer and closer. We're back to another Christmas season and he proposes! 
Now it's time to meet the parents - up first is Asha's family. Asha's dad is a real hoot who does some classic fatherly hazing to Jake such as giving him a hard time about his rental car, getting on him about not asking for his blessing, and tricking him into eating some real hot chicken. 
They go to meet Jake's dad and it's a different vibe and they end up getting into a bit of an argument about how many kids they'll have. His dad expresses concern over Jake not being ready for marriage. 
Jake's parents are divorced, hence his fathers hesitancy towards marriage, so they go to meet his mom. She's much more excited for them to get married and also excited to show off her knowledge of Indian culture she's learned from pop culture. 
The next day, Jake falls off a ladder when he finds out that he's not the first guy to propose to Asha. She explains to him that her dad really liked this guy but i didn't and I said no. They talk about it though and make up. 
The next day, the families all come together in the most anxiety driven scene in the history of Hallmark. Jake's mom wears a traditional Indian saree and they don't take off their shoes. They get in an argument about where the engagement party is gonna take place. But that's nothing a little Silent Night won't handle.
After going to the Christmas carnival together, both sets of parents have conversations about hesitation on if these two cultures can blend. 
There are some more speed bumps along the way such as Asha and Jake waking up on the couch together, a bit of an argument about what he will wear to the engagement party, and frustration that they double booked on Christmas Eve.
It all comes to a head when they show up late to Asha's families Christmas service because they were with Jake's family. A huge argument errupts which leads to Asha saying that she doens't think this is going to work. 
Samual and Jake Sr talk about how they done goofed and decide to work together to make sure their kids work out. 
Samual apologizes to Jake and gives him his blessing for him to marry Asha. 
Then Samual goes and apoogies to Asha and they have an amazing father/daugther moment.
It's time for the engagement party complete with some traditional ceremonial speeches given by both of the dads. They all dance and Asha and Jake kiss under the mistletoe.
