Chris Bavin travels to the Lincolnshire coast to meet a group of dedicated Bloomers determined to put the 'Great' back into Great Grimsby. Last year their council funding for Bloom was cut and the volunteers had to drop out of the competition, but they are back and have created a social enterprise company to raise funds. Money remains tight, but these gold-winning Bloomers take a huge risk by opting to take on one of the most-deprived estates in their town. To brighten up this area, they tackle a neglected stretch of the River Freshney which flows through the estate. The river is clogged with weeds and rubbish and needs to be cleaned up. They also clear an overgrown jungle at the entrance to the estate and give an old bowling pavilion a floral makeover. But their valiant efforts will be in vain if they can't persuade the residents to stop dumping rubbish.

Chris Bavin meets a group of extraordinary Bloomers who must start from scratch every year after their gardening efforts are literally washed away. Tewkesbury in Gloucestershire is at the confluence of four rivers, which makes for a lovely setting, but one that devastates the town to a greater or lesser degree every year when the waters rise and flood the town.
