Asterix and Obelix: God Save Britannia

Julius Caesar lands in Britain, where a small village still holds out bravely against the Roman legions. But the situation becomes critical and the villagers have not got long to live. Anticlimax, one of the villagers, seeks volunteers to go seek help from his second-cousin Asterix the Gaul and bring back a barrel of "magic potion" from the Breton village of the indomitable heroes.
