Why is 1 of 20 tomato plants not producing fruit?

Question

I planted 20 hybrid tomato plants and all but one are blooming and producing fruit. The one plant not producing fruit is a Better Boy while the next two adjacent plants are Better Boy and producing with out issue. The plant that is not producing seems to have heavier stems, slightly smaller leaves and blooms, but does not set fruit. Plants are spaced 4 ft. apart in full sun in an area void of tomato plants last year. All plants are in cages and the Better Boy that is not producing is 39″ tall while the other two are 52″ tall. While I understand the possibility of a seed mix up, that does not explain the lack of fruit. The plant is in the middle of the row and not at the end of row near sod or other plants. Any idea as to the cause, and a solution. I will provide a picture of the 3 Better Boy plants and identify the one not producing and a close up of leaves and blossom. While this plant has numerous blossoms the other 2 appear to have more blossoms.
