Plot

Julius Caesar successfully conquers all of Britain, unaware his men know that one rebel village still holds. Sensing his chief does not have much hope of lasting much longer, Anticlimax decides to travel to Gaul and find his cousin Asterix, in order to secure some of the Magic potion that his village uses to hold back the Romans. The druid Getafix obliges to the request to supply a barrel of potion to help, upon his arrival, with Vitalstatistix assigning Asterix and Obelix, accompanied by Dogmatix, to transport it to Britain. While travelling across the English Channel, the group rescue a Phoenician merchant from pirates, who rewards Asterix with a small bag of mysterious herbs for their assistance. As they resume, the group encounter a Roman galley, much to Obelix's delight - due to missing them in recent weeks - and board it to satisfy his need for a fight.
