Tagann eachtrán chuig bunscoil. Cad a thug anseo é? Conas ar tháinig sé? Níos tábhachtaí fós, conas a rachaidh sé abhaile arís? Tá an t-ádh leis go bhfuil Gaeilge ina aistritheoir idir-réaltrach! Agus an seomra á scrúdú aige, agus cairde nua á dhéanamh aige le muintir an domhain, foghlaimíonn sé nach bhfuil an pláinéad seo chomh difriúil óna phláinéad féin. Ach chun dul abhaile, ní mór dó scéal na seachtaine is aite riamh a chur le chéile, agus aghaidh a thabhairt ar an dúshlán ollmhór sin - na Sceitimíní! 

A young alien is transported to earth. Why is he here? How did he get here? and more importantly how does he get home? Luckily for him, his intergalactic translator speaks Irish. As he explores the room and befriends the earthlings around him, he discovers that this world is not so different from his own but to get home, he must piece together the craziest week ever and overcome the dreaded Sceitimíní.
