PAL PAL DIL KE PAAS is a love story set amidst the beauty of Himalayas and the ugly politics of Delhi. Karan Sehgal (Karan Deol) resides in Manali and is the owner of the very popular Camp Ujhi Dhaar. He lost his parents in an avalanche when he was 10 while they were on the hunt for the elusive snow leopard. The costliest trekking package offered by Camp Ujhi Dhaar is worth Rs. 5 lakhs and involves solo trekking with an expert. Vlogger Sahher Sethi (Sahher Bambba) from Delhi, who has just taken a break from her boyfriend Vinny (Aakash Ahuja), signs up for it as an excuse to escape from her nagging relatives who are to visit her house.
The expenses are borne by her company for which she vlogs. Sahher is known for tarnishing the image of hotels and tour companies with her acidic vlogs and she's all set to do the same with Camp Ujhi Dhaar too. She believes charging Rs. 5 lakhs is akin to a daylight robbery by the camp. Karan himself takes up the responsibility of taking Sahher for the 5-day trek. Initially, she detests Karan and says negative stuff about him in her daily vlogs. Karan, on the other hand, too doesn't think too high of Sahher. But slowly, they fall for each other.
Sahher changes her mind and realizes that the trek is the best thing that has happened to her. She returns to Delhi and continues to be in touch with Karan. She breaks up with Vinny, infuriating her. But he doesn't show and pretends to be cool with her decision. Karan, unable to survive without her, reaches Delhi when she hints him that she misses him too.
They profess their love for each other. Vinny decides to put a devious plan into motion to bring back Sahher in his life. He's aided in this plan by his elder brother Sushant Narang (Aakash Dhar), who's running for the elections and the son of Ratna Narang (Meghna Malik), who's into politics since two decades. What happens next forms the rest of the film.
