Honour (2017)

Lee and Sonny are very close 11-year-old friends who are goaded by an older boy to break into a flat they think is uninhabited as an initiation to join his 'crew'. Their mission is to bring back something of value but what they find instead is an inert, probably dead, man inside. Lee and Sonny are forced to confront their naive notions of masculinity and codes of honour when the dead man turns out to be a wanted criminal in hiding.

Unfortunately the movie Honour is not yet available on HBO Max.
