Alvin in veverički je animiran film o fiktivni glasbeni skupini treh veveric. Alvin, Simon in Theodore so glasbeno nadarjeni veverički, ki so ostali brez doma. Drevo, na katerem so živeli, so namreč posekali in ga skupaj z njimi poslali v Los Angeles. Tam spoznajo skladatelja Davida Sevilla, ki ga muči ustvarjalna kriza, toda veverički mu rade volje pokažejo svoje glasbene sposobnosti. David hitro spozna, da bi mu Alvin, Simon in Theodore lahko prinesli uspeh, zato vsi skupaj sklenejo, da bodo poslovno sodelovali: David bo pisal pesmi, veverički pa jih bodo izvajali.

Navihani veverički Alvin, Simon in Theodore uživajo v svetovni slavi svojih pevskih dosežkov, toda njihov skrbnik David se odloči, da ne smejo zanemariti izobrazbe. Pošlje jih v šolo, kjer se morajo soočiti s številnimi nepričakovanimi izzivi, dodatne preglavice in prve ljubezenske dileme pa jim prinese trio prebrisanih in pevsko zelo nadarjenih veveričjih spogledljivk. Zabave in smeha polni glasbeni dvoboj se lahko prične! Alvin, Simon in Theodore začasno postavijo svojo slavo na stranski tir in se lotijo učenja. To ni lahek prehod, saj izkusijo marsikakšno tegobo šolskega življenja: nasilneže, klike, potegavščine, strogega ravnatelja. A kar je najpomembnejše: njihove šolske dogodivščine postavijo na preizkušnjo predvsem družinske vezi.

V novem nadaljevanju, skozi niz nesporazumov, so Alvin, Simon in Theodore prepričani, da se je Dave odločil, da bo predlagal za svoje novo dekle v New Yorku. Tri veverice se odločijo za pot, da jo preprečijo, vendar imajo le tri dni, da jo ustavijo in hkrati zmanjšajo možnost, da bi dobili strašnega polbrata.

Veveriček Alvin se z bratoma in prijateljicami veveričkami ter človeškim prijateljem Davom opravi na križarjenje preko oceana. A nesreča nikoli ne počiva – obilica nerodnosti in trenutek nepazljivosti sta dovolj, da se mali glodavci znajdejo na osamljenem otoku. Med iskanjem hrane in drugimi pustolovščinami v džungli si pomagajo z zabavnim petjem in svojimi nemogočimi vragolijami. Da bi našli pot domov, pa morajo združiti moči in prisluhniti živalskemu nagonu, ki so ga v mestu že povsem pozabili. Zabavni veverički Simon, Theodore, Brittany, Jeanette in Eleanor se vračajo v nepozabnem tretjem delu.

As Alvin struggles with nightmares involving werewolves, the school play of Jekyll & Hyde is in jeopardy when the lead, Alvin, is suspended. In an attempt to boost his confidence, the principal suggests Theodore, who's suddenly going through some canine changes.

The Chipmunks and the Chipettes go head to head in a hot air balloon race, and the winner gets $10,000. Unbeknownst to the participants, the "race" is actually a diamond smuggling ring!
