Tien and Susumu

S1 E5: In a senior care home, a resident's tablet was stolen. Koda questions Vietnamese worker Tien. The Vietnamese interpreter, Imai, notices bruises on Tien's body, leading Koda to suspect that Tien may have been assaulted. Meanwhile, Arikino encourages Imai, who is overwhelmed by the harsh realities of foreign workers. Koda's investigation eventually leads her to Tien's "friend" Susumu.© NHK
