In the quiet, off-season seaside town, Detective Inspector Wiggly finds himself amidst rain and desolation as he seeks refuge in Berties fish and chip shop. With raindrops cascading down his rugged features, Wiggly clings to a local newspaper for shelter and shields his attire from the downpour with his trench coat. Inside, the regulars enjoy their chip-based orders while Wiggly engages with Bertie, the shop's owner.

As Bertie takes Wiggly's order for 6 battered sausages, a casual conversation unveils the detective's personal struggles and the somber undertone of his day.

Sharing more than just a meal, Wiggly confides in Bertie about a murder that occurred the previous night, a revelation that leaves the chip shop owner horrified.
