Potato. Drowning in a sea of debt, Eric desperately seeks to improve his standing with his boss in the last ditch hope of a pay rise. So he volunteers to entertain a troublesome but important client, the Chairwoman of the potato development board Mrs Bont. Come the evening in question everything for once seems to be working out well. The table is laid, the food is out, the guests are about to arrive. Then Eric finds out he is just one potato short.
