Season 4 of The Expanse will be available to Amazon Prime subscribers starting December 13th, 2019. This politically charged, space-based, action drama takes place in the not-so-distant future, where man has expanded his reach throughout the solar system. The series follows the growing tensions between the United Nations-controlled Earth, the vast military power of the Martian Congressional Republic, and the working-class “Belters” that mine asteroid belts for resources. After a tragic accident strikes an ice mining vessel at the start of the series, a vast conspiracy emerges that could spark all-out war. Season 4 promises a "blood-soaked gold rush" as factions fight for resources on a newly discovered planet.
