In the wake of a marital break-up, Dave finds himself living in the storage unit in which he keeps his belongings. Dave is accompanied by his fellow inhabitant, the borderline psychotic Geoff, and cultured security guard Ron.

In series one Dave, having been dismissed from his job, is coming to terms with his marriage break-up. He books a pod in a self-storage unit, intending to keep his life possessions there. However, when he realises that he hasn't arranged somewhere to stay, he is forced to store himself alongside his stuff.

The Storage Garden is run by Ron, a well-cultured security guard. Also a regular customer is Dave's neighbour, Geoff, who serves as a reminder to Dave of what people can become without regular social interaction. Dave's family, of course, attempts to help him out of his situation, with his sister, Rosie, doing somewhat better than his father. As Dave finds himself stuck in the world between real life and packing crates, he begins thinking back to the break-up of his marriage to Sarah.
