Your tomato plant appears to be suffering from "physiological leaf roll". This condition is the plants response to stressors such as heavy pruning, heat stress, water stress, too much nitrogen, root damage, among others. Although it looks bad, it should still product fruit. Some cultivars are more susceptible than others. Viruses and herbicide damage can also cause leaf curling but do not seem to fit with the plant in the pictures.  It is curious, however, that the others plants are not exhibiting the problem (to the same extent).  Take a look at the following links for more information:
