En aquesta ocasió els nostres amics hauran d’evitar que es construeixi un parc d’atraccions en el lloc on hi ha la seva llar. Tornen els esquirols més divertits del cinema!
L'esquirol Surly i el seu amic Buddy planegen donar el gran cop de la seva vida a una botiga de fruits secs. Pràcticament sense adonar-se, es veuen involucrats en l'atracament a un banc que a l’hora estan planejant uns gàngsters.
After breaking out of a rehabilitation zoo, Frankie, a squirrel with all the angles, returns to his forest. He learns from his dim-witted best friend, Cody, a porcupine and street-con, that while he was in lock-up, the entire forest was picked clean by The A.C.O.R.N.S. Institute (Alternative Cosmetic Oils for Regenerative Natural Skin-care). No acorn was left behind. With winter just around the corner, it's a potentially devastating blow to all forest critters. So, Frankie has no choice but to bust into the brand new, state-of-the-art, rodent-proof A.C.O.R.N.S. Processing Plant and take back all of the acorns! Though a seemingly impossible heist, success would not only save the lives of his forest friends, but it would also give Frankie a chance to win back the love of his life, Lola, a local "show squirrel." Sadly, Lola has been burnt by too many of Frankie's false promises in the past.
When Petra spends an evening with her best friend Sanna, Sanna asks how she knew she was bi. Petra tries in earnest to show her the truth.
