Love Island USA may be over (aside from the reunion), but Netflix is extending this summer of reality TV. The Ultimatum: Marry or Move On, the streaming giant's controversial dating show, has returned for a fourth season of partner-swapping chaos. From the producers of Love Is Blind, The Ultimatum recruits couples at a crossroads to test whether they're really meant for marriage by splitting them up to see if the grass would be greener with someone else. After two trial marriages—one with a new match and another with their original partner—each couple has to decide whether to get engaged or part ways.
Season 4 of the divisive reality show brings three couples to Sin City to work out issues ranging from broken boundaries to parental pushback to emotional barriers. (This installment also marks the first time a couple has been kicked off the show.) Below, read on for a primer on the stars of The Ultimatum season 4, ahead of the July 22nd finale.
