Four couples make one last-ditch effort to save their relationship. The couples leave for Curaçao for a radical relationship therapy, in which they temporarily change partners. Under the supervision of psychologist and sexologist Irma van Steijn and relationship therapist Jeroen Stek, the participants are temporarily linked to someone else. The intention is that this makes them aware of their own needs, wishes and interests and what they value in their own partner. Do they discover what is going wrong in their own relationship thanks to the temporary partner? Will it be staying or separating after the 'switch therapy'?
