Elliott, a teenage girl living on her parents' cranberry farm in Muskoka Lakes, Ontario, has three weeks left before she leaves for university in Toronto. She spends her summer days boating with her friends Ro and Ruthie, working on the farm, and engaging in a romance with Chelsea, a girl she has had a crush on since grade eight.
On a night out camping to celebrate her eighteenth birthday, Elliott takes mushroom tea with Ro and Ruthie; all three experience psychedelic trips. Elliott sees a woman appear next to her who says she is her older self. Though Elliott is skeptical at first, the woman proves she is the future version of herself by showing a scar on her ribcage and sharing knowledge of Elliott's asymmetrical breasts. Older Elliott, a PhD student, gives her younger self advice by suggesting that the younger Elliott treasure her time at the farm and bond with her family. She also mysteriously tells her to avoid a boy named Chad. The pair fall asleep in the tent, and Older Elliott puts her number in younger Elliott's phone under the name "My Old Ass".
The following day at her home, Elliott remains in contact with Older Elliott by phone. She decides to spend more time with her younger siblings Max and Spencer. One day while skinny-dipping in the lake, she encounters a boy who is spending his summer working for her father. When he reveals his name is Chad, Elliott remembers Older Elliott's warning and resolves to keep her distance from him. However, as Chad shows himself to be likeable and thoughtful, she finds herself becoming attracted to him, which confuses her as she thought she was a lesbian.
Elliott learns from her brother that her parents are selling the farm after she leaves. When she confronts her father about it, he tells her how she was always looking forward to leaving anyway, but she expresses that she thought the farm would always be there to come back to. Nevertheless, he tells her the family got a good offer they cannot turn down and Elliott must accept it.
One day, Elliott asks Chad to accompany her to help sell her boat. On the boat, they confide in each other about how fast life can go and Elliott says she wishes she could stop time. They share a kiss, causing Elliott to freak out and flee. In an attempt to make Older Elliott appear again, Elliott goes to Maude Island with Ro and gets high on the mushrooms. During her trip, she does not see Older Elliott but hallucinates that she is Justin Bieber, performing "One Less Lonely Girl" and giving Chad red roses. The next day Elliott talks to Ro about acknowledging her bisexuality.
Elliott takes Ro and Ruthie to meet Chad, who reveals he found a buyer for the boat. He and Elliott take the boat out for one last ride, but the motor falls off mid-ride as it starts raining. The pair get to a lookout shack, where Elliott discovers Chad already attends her university. She tells him she used to think she was gay, and that "a friend" told her it would be a bad idea to get close to him, but that so far she likes him and is going to go with her gut and ignore what her friend said. They admit their mutual feelings for each other and have sex.
After Chad walks her home, Older Elliott reappears to Elliott. Older Elliott reveals why she warned her against Chad—Chad will die and she cannot save him. Because of this, she does not want younger Elliott to experience the same pain. However, Elliott says she will go ahead and fall in love with Chad anyway because the experience is worth it. Chad returns to bring Elliott her shirt and can surprisingly see Older Elliott. The two awkwardly introduce Older Elliott as Elliott's "uncle" Michelle, and Older Elliott gives Chad a tearful hug. She says goodbye and leaves forever, now encouraging Younger Elliott to experience this tragic love. Elliott receives a voicemail from Older Elliott telling her not to live for the past or future, but for herself in the present.
