Melnā māte cenšas sagrābt varu pār pasauli, krājot asaras no visiem, kas raud par nelaimēm un aizgājējiem. Viņa gribētu nogalēt Princesi, jo tad raudātu visa karaļvalsts un Melnā māte iegūtu absolūtu varu. Nejaukajai raganai izdodas ieslēgt Princesi stikla zārkā, taču Baltais tēvs stājas viņai ceļā un rada stāvu ledus kalnu, kura galā Princesei nu jāguļ septiņi gadi un septiņas dienas; tikmēr drosminieki var mēģināt Princesi izglābt. Antiņš un viņa brāļi arī dodas palīgā.

Latvijas Tautas dzejnieka Raiņa lugas motīvos balstīts senu arhetipu stāsts – divi gudrie brāļi un trešais muļķītis, tēva novēlējums, ļauno un labo spēku pretstāvēšana, daiļā princese, viņas tēvs karalis un kaimiņu princis ar ne visai labiem nolūkiem. Un trīs mēģinājumi, trīs brieduma pakāpes, kas nepieciešamas mērķa sasniegšanai. Šis vispārpazīstamais dramaturģiskais zīmējums stāstīts vispārsaprotamā kinovalodā, lai sasniegtu skatītājus arī citās valstīs ārpus Latvijas.
