André Joyal has worked like a dog his whole life to build a business that he could leave to his sons. But now, sales are in freefall and his best customer - a long-standing friend of his - has decided to change suppliers. As if that weren't enough, his wife, Diane, wants to go back to work after several years at home.

André will do anything to get Jean Langlois back as a customer. His company's survival depends on it. He also reluctantly agrees to go to Mayor Valcourt's golf tournament, hoping to finally land a contract with the city. Encouraged by his boss, Gaston gets creative to close deals, no matter the cost.

Diane has her first day of work at the shop. Jean Langlois has once again stopped ordering. On the verge of ruin and at the end of his rope, André looks for solutions: is he prepared to compromise his integrity to land contracts with the city? Gaston visits a rather eager female customer, and Philippe starts imagining a future far from the shop…

The whole family is in shock following Vincent's accident. The staff do what they can to support André through this difficult time. After learning that the big hardware stores are now selling doors and windows at a fraction of the price, André heads over to check out the competition. Philippe is nervous about announcing some big news to his father.

André's world crumbles even more. Between conflict with his wife, Diane, the shop's financial difficulties, and Philippe's audition at a comedy school, André is teetering on the brink. Diane makes a stunning discovery about her husband and Gaston gets an unexpected visit from his wife at the glass shop.
