The Man Without a Past (2002) on Netflix

Plot summary

He steps off a night train in Helsinki and dozes on a park bench, where three criminals set upon him. Declared dead at the hospital, he comes to and walks out in bandages. The Nieminen family, who live in a discarded shipping container at the harbor, find him on the shore and nurse him back to health, but his memory has gone; he cannot recall his own name. Anttila, a harbor guard who places people in empty containers, arranges one for him. The employment office turns him away for lack of a name. He meets Irma, a Salvation Army volunteer, who gets him work in the organization's thrift store, and the two grow close.
