Young-goon works in a maddening dead-end job making transistor radios. Flipping, she insists she's a cyborg and that she only needs to lick batteries for sustenance rather than eating. She's sent to a psychiatric ward where she's befriended by schizophrenic kleptomaniac Il-Sun. The two damaged souls fall in love, combating the staff at the hospital as Young-goon becomes a battle-bot in one of the many fantasy sequences shot in surreally bright colours that punctuate this unique, delightful film.
