At the office, Evelyne must hold the fort despite François' terrifying crisis. Who can she count on? François' actions divide Marc-André, Patrick and Vincent. Could this be the beginning of the end for this once inseparable quartet? The twists and turns of the last few days shake up the very essence of oneself and give way to major rethinking in friendship, love, career choices...

After the latest upheavals at Olstrom, Marc-André and Dominique will have to put their past aside and join forces to ensure the future of the company. Meanwhile, Florence decides to get the upper hand on her bullies, but how will she do it? Having no news from François, Evelyne worries that she has gone too far. Nothing is more dangerous than a man who has nothing left to lose.

To keep the company afloat, Marc-André, François, Evelyne and Dominique will have to stick together and relearn how to work as a team. Will they be able to adjust to their new reality? Evelyne discovers information that could compromise Olstrom's future. Vincent rediscovers a great bond with Stéphanie. He listens and tries to help Florence as best he can. Will they become the family they once were?

François takes advantage of Taschereau's hospitalization to prove to him that he is ready to assist him, but his leadership is not unanimous. If Taschereau ends up bowing out, who will he have chosen to take over as CEO of Olstrom? With the pitfalls of the trial with Evelyne, the toxic relationship with his father and Ukave's deal, François is driven by the energy of despair. 

The quartet is reunited for a golf tournament, each with a different goal in mind. With Marc-André on a mission to appease the Minister of Energy and Economy, François at the end of his rope, Patrick on a "mush trip" and Vincent under Isabelle's spell, the day promises to be very eventful. Meanwhile, Florence, who finds a little more freedom, is not safe from the nastiness of her classmates.

No longer able to remain indifferent to Marc-André's distress, Vincent lets his guard down and tries to reconcile with his friend. Marc-André falls completely under the spell of Isabelle, his new flame, or his new lifeline? Their plan to protect the family nest shows flaws when Patrick and Marie-Michèle's children suspect they are separating. Patrick, helpless, successfully tries to reconnect with his "Eros".

The growing complicity between Patrick and Clara brings a breath of fresh air to Olstrom. François being obsessed with Évelyne's new lifestyle, it is Marc-André who must take over on the Ukave file. Would Isabelle be an important ally for this file? Will Évelyne, looking for challenges, be tempted by a new job offer? As for Vincent, as much as Florence's presence in his life does him good, he still feels anger towards Marc-André.

Taschereau, who is at the end of his career, must ensure his succession. Thanks to his general appreciation in the office, Patrick falls into the boss's sights and he is flattered, but is he really the only potential candidate? Although Vincent is sensitive to Florence's distress, those around him are astonished by his arrogance and bitterness. He is back with a desire for revenge.

With the unexpected departure of an employee, the Olstrom team will have to pull together to face the next "deal of the century". Will a reconciliation between François, Marc-André and Patrick be necessary? In the process of separating, Patrick makes huge compromises to protect the family nest. Will he be able to assert himself in his new reality as a couple? 

A few months after François' arrest for insider trading, it's Marc-André and Evelyne's turn to form the most prolific duo at Olstrom. With François now cleared, will he return to Olstrom? Without the support of Vincent who is nowhere to be found, Florence doesn't know how to live with her new reality. Patrick tries to return to Olstrom, but is still recovering from depression.
