When a lottery ticket hits the jackpot, David, Jess, Léo and Samia dive into luxury before realizing that collecting the cash won't be that simple.

Desperate to claim their prize, Jess poses as a lost daughter while David and Léo sneak into a hospital with a stretcher and no plan.

As Victoire enters the fray, David spirals over unpaid debts and Léo gets tangled in family drama after an expensive night out hits home.

When Léo leaks word of their win, Jess scrambles to spin a cover story, but her plan sends cash flying around school and draws all the wrong attention.

Over champagne and salmon, the gang lives large until cryptic texts threaten to expose their schemes and Tom takes a shot at cracking a strange code.

David and Samia chase a suspected blackmailer through the city, while Jess fast-tracks a big first - just in case potential jail timehugs the vibe.

The group finds a solution to end the blackmailing, but once again they need Victoire's cooperation. Léo finally admits his true feelings.

David's birthday bash is the teens' final shot to flip the script. As plans unfold, it becomes harder to understand who can actually be trusted.
