Three youngsters, Alia, Faraz, and Munmun, each with a mission of their own take up an internship at Manali's Grand Mountain resort. While Alia is there to unearth the truth about her mother Heena's murder, Faraz wants to prove that his father, Wasim, was not having an affair with Heena. Meanwhile, Munmun is at the hotel to leave her past behind and start life afresh.
After the interns are assigned work on the basis of their capabilities, a hotel guest tries to commit suicide. But Alia steps in and handles the situation smartly. In another instance, Faraz exposes a guest who is trying to make false allegations against the resort. Impressed with the interns, Arshad, the hotel's owner, organizes a party where Faraz kisses Alia and where she later sees Munmun secretly collect a packet from an unknown person.
Arshad's mother, Meher, is sent to a rehabilitation centre. When this news breaks out, he tries to find the person who leaked the information. Meanwhile, Amaira tells Alia that her feelings for Faraz cannot create a rift between them. Naaz and Javed meet after a long time. But she mistreats Javed as he owns a small share in the company. Munmun continues to get messages from Barkat and finally reveals her story to Alia.
Arshad briefs the interns about an event that is being hosted at the resort and warns them against making any mistake. One of the award winners ends up getting drunk at the after-party and is escorted to her room by Faraz. However, the woman accuses him of raping her leading to his arrest. Later, after Arshad bails him out, Faraz's true intentions are revealed.
Faraz arrives at Trinity and grows closer to Amaira. During a fashion show, Alia and Faraz turn up as showstoppers and manage to save the event. Meanwhile, Arshad is stunned to see Faraz at Trinity and finds out that Naaz is the one who got him here. Alia manages to get some important information about her father and tries to reach him at any cost.
Mehar's health worsens as she starts missing her family and tries to escape from the rehab facility with the help of a mysterious guy. Munmun's twin sister, Shonali, appears and she is completely devastated to find out about her sister's death. Paresh finds the culprit who stole the money and falsely accused Alia of the theft. Alia then gets drunk and confronts Arshad and they have an emotional moment.
Aalia is aghast when she discovers Balraj's connection with the Khan family and is threatened by him. Meher returns home after her long stay at the rehab but feels dejected about Arshad and Javed's unhappiness and ignorance towards her. Arshad can't stop hating Aalia and breaks down in her presence which brings them closer. Aalia, in her agony to meet her father, stands strong against Balraj and gets a lead on Imraan.
Arshad asks Aalia out on a date, but she fails to make it which irks him. Shonali and Raghav are determined to get their hands on any evidence against Balraj, and Amaira is desperate for Faraz's attention. After canceling his date with Amaira, Faraz spies on Aalia and finds her at a Dargah with Imraan. Meanwhile, Shonali tracks down Balraj and sets up a meeting with him.
Imraan feels that someone is spying on him and decides to move out of his house. Arshad is upset with Aalia, who later reveals to him that she has found her father, and with Meher for interfering in his life. Meanwhile, Faraz is stunned when he comes to know about the Jaffri family from Fareeda. Javed finds out that Aalia is Imraan Jaffri's daughter and Naaz tells Aalia to get to Javed if she wants any information about her father.
Amaira gets injured and is hospitalized. Ejaz tries to get closer to Meher and begins to understand her better than the other family members. Faraz tries to speak to Aalia about their families but she refuses to talk about it. Later, Aalia tries to contact Javed regarding Imraan which frustrates Arshad.
Faraz kidnaps Javed and plants all the clues against Aalia and Paresh, which Ejaz discovers later. Arshad refuses to believe Ejaz and doubts Aalia. Ejaz decides to take Aalia and Paresh to the police station but is saved by Aalia when some goons attack him on the way. Ejaz realizes that Aalia can't be the culprit and decides to look for further clues.
Imraan comes face-to-face with Javed and threatens to destroy him if he disrupts Aalia's life again. After the clues lead him to Faraz, Ejaz goes to arrest him and comes to know that Arshad's life is in danger. However, just when Ejaz reaches to save Arshad, he sees his car falling off the cliff after getting hit by another vehicle.
The search for Arshad is on. Meanwhile, Ejaz suspects that Javed is hiding something from him. It is revealed that Imran had confronted Arshad about what transpired in room no. 402, and that Faraz is aware of Javed's drug business. The person behind the mask is finally exposed, and it is none other than Javed.
Aalia, Ejaz, and Javed are shattered by Arshad's death. At the funeral, Aalia says her final goodbye while Ejaz vows to punish the murderer. Meanwhile, Raghav and Shonali decide to get to Balraj. Aalia confronts Faraz at the police station, where he reveals Javed's involvement in Arshad's murder. Faraz blackmails Javed and asks him to bail him out.
Ejaz bails Faraz out, which baffles everybody. He later confronts Javed as to why he wanted Faraz to be released. Balraj too confronts Javed. Ejaz tries but fails to find more information. Meanwhile, Amaira is devastated upon learning about her mother's past and is later astonished when she finds a video on Faraz's phone.
Naaz gets worried about Amaira, and Aalia comforts her. When Faraz receives a termination letter, he gets into an ugly fight with Ejaz. Meanwhile, Shonali tries to get information about Balraj, and Ejaz breaks into Faraz's room, where he finds out his Lucknow address. Faraz notices the accident video shared on Amaira's phone and tries to smother her.
Aalia finds Amaira in a critical condition and rushes her to the hospital. Faraz loses his phone and comes to the hospital in search of it when Aalia catches him red-handed. Meanwhile, Ejaz reaches Lucknow and gets all his answers from Farida. Here he also confronts Javed. Aalia and Imran discuss how they can get Javed's confession.
