He came from a faraway galaxy. A place that you can only imagine when looking up at the clear night sky—somewhere beyond the twinkling stars. He is… Zonad! Well, actually, he's just an overweight bloke who just broke out of rehab (and happens to be wearing a tight, red vinyl bodysuit and helmet). Promising to return for a fellow inmate injured during the getaway, Zonad instead ends up in the quaint Irish hamlet of Ballymoran, a town with all the modern-day conveniences but that seems to be stuck in an episode of Father Knows Best. He is discovered in the Cassidy house, and after a night of stargazing the family is quick to label him a visitor from outer space.
Soon Zonad is a local celebrity, milking everything he can get: free room and board from the Cassidys, bottomless drinks at the local pub, and the adoration of all the town's teenage girls (especially the lovely Jenny Cassidy). Everything is going great for Zonad, until his fellow escapee shows up as… Bonad! Directors John Carney (director of Oscar® winner Once) and Kieren Carney have concocted a hilarious, zany romp that goes down like a nice pint of Guinness.
