02E05 - All the World Is Birthday Cake

When a semi-primitive society finally calls out in space by radio, the Orville picks up the signal first and rushes there. Captain Ed's party is warmly welcomed as both sides want to discover the other. Suddenly, the state dinner turns into an outraged break-off as soon as Bortus and Kelly mention having their birthday- both are arrested as 'Gilliacs' and sent to a concentration camp, the rest of the party send back to the ship 'never to seek contact again'. It turns out the society has an astrological prejudice, causing births to be artificially shifted to avoid ill-boding months destining for a chained life as predestined criminals, while the next month means admission to the ruling elite. The Orville is forbidden by the admiralty to liberate its crew duo, hence seeks a way to outsmart the star sign bigotry.
