Dylan, Lizzie, Gina, Eric and Tyler bid farewell to summer with one last mission: to foil Thornton’s devious plans.

As the sun begins to set on Junior Rescue season, a staff shake-up leads to a new normal — and a “special assignment” — for the Flounders.

Mystery and mischief collide as the boys partake in a super-secret project, and the girls team up for a sticky situation.

Things take a tender turn as Eric unpacks his feelings. Meanwhile, Gina encounters a new rival, and Dylan opens up to Tyler.
