The village of Trotford is like the other small towns in Equestria. Quiet, unassuming, very nice. The stallions, however, are flighty, and the mares are upset they can't find a decent husband.
The stallions are satisfied with things, being free and clear to just have their own fun when they like. Nothing seems likely to change, and yet, things start to. More marriage, with the husbands so very happy and satisfied with their new lot in life. Some investigation is quite necessary...
