Chris is not getting along with boyfriend Sandor and has an affair with parole officer Dennis. Dennis invites the couple to dinner with his ex-girlfriend Jan. At a picnic on the beach, Jan meets lifeguard Phil, who later sleeps with Chris and moves in with the other five. Phil brings in a person, lawyer Elaine. The "group marriage" of the six of them attracts media attention, which brings trouble and prejudice.
Unfortunately the movie Group Marriage is not yet available on HBO Max.
