Set against modern-day Tokyo, RENTAL FAMILY follows an American actor (Brendan Fraser) who struggles to find purpose until he lands an unusual gig: working for a Japanese "rental family" agency, playing stand-in roles for strangers. As he immerses himself in his clients' worlds, he begins to form genuine bonds that blur the lines between performance and reality. Confronting the moral complexities of his work, he rediscovers purpose, belonging, and the quiet beauty of human connection.
