Pallet on the Floor (1986)

One of Those Blighters.

A murderous black comedy set in the 1960s. Sam (McCauley) and his small band of hard-drinking and eccentric friends are having a night of it when a drunk truck driver, Jack (Bach), attacks Sam's Maori wife Sue (O'Brien). In the struggle, Sam and friends end up killing Jack. None of them regrets this, but it has been observed by Miriam (Gruar) who decides to blackmail Sam. Jack's brother Joe (Napier) comes looking for revenge and ends up being killed by Basil (Spence). Their jobs at the freezer works are terminated, and Basil has his own idea about how to get out of their troubles.
