Retired couple Arthur (Bernard Hill, Wolf Hall, The Lord of the Rings films) and Martha (Virginia McKenna, The Camomile Lawn) Goode live a quiet suburban life, tending to their garden and socializing with friends at their club.

Dressed in masks and armed with cucumbers as guns, the unlikely criminal duo makes national news. But with detectives Sid (Alun Armstrong, New Tricks) and Stringer (Brad Moore, North v South) closing in on them and their beloved club in talks to become a supermarket, the Goodes enlist their friends' help to pull off one last, audacious heist. This fast-paced comedy-drama features an internationally renowned cast, also including Una Stubbs (Sherlock), Phil Davis (Poldark), Ellen Thomas (EastEnders), Sue Johnston (Downton Abbey), and Simon Callow (Four Weddings and a Funeral)
