Jérémie Archambault starts a new life with her father and her brother, far away from the city, and gets a job as a lifeguard for the summer at the Domaine du Lac. Working at the beach is a new start for her, and she’d like to put her heavy past behind her. She joins a team of five lifeguards: Raphaëlle, Camille, Olivier, Thomas and Maxime. Rapidly, Jérémie realizes that she’s involuntarily disrupting the group dynamic.

It’s Jérémie’s first day of work … and Raphaëlle is making her life difficult! Raph holds Jérémie responsible for her boyfriend’s misfortunes. Add to that Olivier, her cabin roommate, who turns out to be hard to pin down. After a bad performance for Thomas at his swimming competition, Jérémie gets chewed out by Philippe Cinq-Mars, her boss, for having “dared” to give Thomas tips. Her first day is turning out pretty bad … until her new friends come to her rescue.

Day off for Jérémie. She and Maxime planned to spend the day together, but their plans are interrupted by a surprise visit from Mathieu and Benjamin. Jérémie decides to spend time with her family … which brings back some bad memories. For her part, Raphaëlle has trouble containing her jealousy when it comes to her boyfriend Thomas.

Thomas is having trouble getting over his failure at the swimming meet, which causes frictions with his girlfriend and his father. During that time, Olivier and Jérémie are getting closer. The two roommates are getting along rather well … but they’re also hiding elements of their past from each other. During that time, Camille is trying to repress an impossible love… Is it possible that she has feelings for her best friend’s boyfriend?

Jérémie, Max and Olivier have decided to enjoy their day off by going camping. It’s not the best moment because there’s a problem at the Domaine du Lac: Thomas has disappeared! Everyone is worried and looking for him. While camping, tensions run high and Jérémie, Olivier and Max’s expedition takes a wrong turn for one of them.

Thomas shows signs of life. Jérémie encourages him to face his problems. Max and Olivier, for their part, are having a falling out. The camp trip didn’t turn out like Max hoped, and he blames Olivier. Camille falls under the charms of a boy … who might not be interested in her for the right reasons.

If Jérémie and Olivier wished to live the early days of their relationships in the greatest of secrets, it’s a complete bust. Their relation is revealed for all to see and no one is indifferent! Despite her happy mood, Jérémie is still repressing her past, which seems to track her everywhere. The arrival of Ève, one of her oldest friends, forces her to reveal a bit more.

Motivated by Ève’s recent visit, Jérémie decides to move forward, rather than exhaust herself denying her past. However, moving forward also has its lot of difficulties. That requires Jérémie to trust those she loves and who support her: her family, her friends … and especially Olivier. Will Jérémie reveal to her boyfriend that darker part of her life, even if it means risking being hurt once again?

Jérémie and Olivier are living a perfect life … even if Benjamin spends his days complaining, even if vacationers keep making trouble at the beach, even if the whole world is falling for Raphaëlle. Jérémie, for her part, is still living on her cloud. Free of worries, she has no idea of the drama that’s about to hit her.

All the lifeguards are in shock after a nightmarish night. Will Jérémie and Thomas get out of it unharmed? That’s without considering Olivier, who’s been missing since he showed that less attractive side of his personality. Jérémie doesn’t know what to do to get out of this new infernal spiral.

Jérémie feels like everyone is appropriating her problems, like no one is listening to her. But for her part, what does she really wish for? Jérémie finds strength and courage that she didn’t know she had. Unfortunately for Jérémie, Olivier doesn’t have that strength.

The unannounced arrival of Anne troubles Jérémie. She feels like her mother has been undoing all the efforts she’s made to get better. But Anne is as headstrong as her daughter. She has no intention of leaving, even if her presence is disruptive for Jérémie, Mathieu and Benjamin.

Jérémie keeps trying to pierce the mystery around Olivier, without seeing that he’s making efforts to get closer to her. Will what Olivier has to offer to Jérémie still suit her needs? Jérémie stop resisting her mother’s presence, and finally talks to her frankly. But her mother’s reaction is far from being what she hoped for…

Jérémie is at a turning point in her relationships. What is she expecting from Olivier? Is it a good idea to remain cabin mates? Will the gulf between the two ex-lovers get even deeper? And with her mother, is it still possible to fix what’s been broken? The decision is now Jérémie’s.

The friendship between the six lifeguards is now going to be tested… What could be better than a BBQ at the trailer to have a fun evening. At least, until it all turns into a session of score settling. Is someone else at the Domaine making Jérémie’s heart flutter?

Jérémie is recovering slowly from her drunken evening. Fortunately for her, an incident forces the lifeguards to close the beach. However, they still have tasks to complete. Jérémie decides to do them with Max, rather than with Olivier. Maxime sees that as a sign from Jérémie … but is it really?

Jérémie gets news from her college program. A program which has nothing exciting for her. Olivier notices and tries to convince her to listen to herself, but Jérémie is refusing to listen. She’s preoccupied by something else. By trying to help Max fix a mistake, one part of her past, which she had tried hard to forget, comes back to haunt her.

The lifeguards are recovering from a tragic accident. For some, they’re feeling anguish and sadness. For others, it’s made them want to intensely live every second. Jérémie, who’s watching over Maxime, thinks she knows exactly how he feels … but she couldn’t have guessed what he’s about to reveal to her.

When Olivier tells her that he’s going on a trip, Jérémie reacts with a frankness that destabilizes him. Stuck, Anne is also forced to be honest with her daughter. This new revelation upsets Jérémie who doesn’t know if she’ll have to do like her mother and lie to Mathieu.

Today is the day of the team triathlon for Jérémie, Camille and Raphaëlle, but an incident forces the girls to change their plan for the day. The lie about her past that Jérémie carries is becoming heavier. What’s more, avoiding a confrontation with Mathieu seems impossible. Will Jérémie find the courage to admit her wrongs?

It’s been a year since Fannie’s death. A commemorative ceremony is organized in her honour. Jérémie doesn’t want to attend. Fortunately, Olivier succeeds in changing her mind… almost. Jérémie chooses another way of reconnecting with her past, which finally allows her to make peace with the death of her best friend.

Jérémie and Olivier realize that their past love lives are very different. Will they be able to get past these differences? The two lovers put their happiness aside, while they help Maxime who’s taken a dangerous path which might have grave consequences this time.

Maxime is having a hard time! Jérémie can’t stand seeing him destroy himself like that. She takes matters into her hands and decides to help him. Unexpectedly, things get out of hand. Max, furious, reveals Olivier’s secret to the group. However, Olivier isn’t the only one hiding something. Jérémie learns that Camille also has a heavy secret.

It’s a big day for Olivier. He is going to see his dad, which he hasn’t seen in years. Anxious over this meeting, he asks Jérémie to tag along. She is trying hard to reassure him, but she quickly realizes that Olivier’s worries were, unfortunately, well founded…

The semester has started and the lifeguards meet up for one last weekend of work. What do they all wish for as the summer is coming to a close? And what about for the next one? It’s time to go over the summer for Camille, Maxime, Thomas, Raphaëlle, Olivier and Jérémie … even if some might not like the decisions of others.
