We present a QCD analysis of the cumulative out-of-event-plane momentumdistribution in DIS process with emission of high p_t jets. We derive theall-order resummed result to next-to-leading accuracy and estimate the leadingpower correction. We aim at the same level of accuracy which, in e+e-annihilation, seems to be sufficient for making predictions. As is typical ofmulti-jet observables, the distribution depends on the geometry of the eventand the underlying colour structure. This result should provide a powerfulmethod to study QCD dynamics, in particular to constrain the partondistribution functions, to measure the running coupling and to search forgenuine non-perturbative effects.Comment: 40 pages, 4 figures, JHEP class included. Version 2 corrects some formulae in appendix B and F and updates the figures and one referenc
