The Lunch Club is up against an Earth-shattering threat in an epic journey through time and in a race against the clock.

Tia and Leo must give it their all to find a secret weapon that will stop The Big Chomp from devouring the planet. They go back in time (again!) and meet old
enemies . . . who maybe aren’t as villainous as they once were.

In the meantime, Mr. Peabody and the members of the other secret clubs are running through rather . . . creative ideas to slow down the arrival of The Big
Chomp and avoid becoming its dinner.

Join Tia, Leo, Mr. Peabody, and their friends one last time. This epic series conclusion is bursting with action, humour, and some unexpectedly sweet moments.
