Mae Obelix wedi colli pob chwant am fwyd, a’i ben ymhell i ffwrdd yn y cymylau… Pam? Gan ei fod e dros ei ben a’i glustiau mewn cariad, dyna pam! Ond mae testun ei serch, yr hyfryd Ffalabala, yn llawn poen a chur gan fod ei dyweddi, Rafingolygix, wedi cael ei orfodi i ymuno â byddin y Rhufeiniaid. Does dim byd i’w wneud ond codi calon yr eneth dlos. Felly mae Asterix ac Obelix yn penderfynu listio yn y fyddin er mwyn achub Rafingolygix. Ac, wrth gwrs, mae cael Asterix ac Obelix ar faes y gad yn siŵr o greu dryswch ymysg byddin Cesar, wrth i’r Galiaid glew sicrhau fod cariad yn drech na rhyfel!

Obelix has completely lost his appetite; his mind is a million miles away… Why? Because he’s head over heels in love! But the beautiful Ffalabala, the girl of his dreams, is pining for her betrothed Rafingolygix, who’s been press-ganged into the Roman army. Determined to make Ffalabala happy, Asterix and Obelix decide to join up and rescue Rafingolygix. But their presence on the battlefield adds to the confusion of Caesar’s war plans, as they try and make sure that love conquers all.
