We present for the first time a measurement of the weak phase 2{beta} + {gamma} obtained from a time-dependent Dalitz plot analysis of B{sup 0} {yields} D{sup {-+}}K{sup 0}{pi}{sup {+-}} decays. Using a sample of approximately 347 x 10{sup 6} B{bar B} pairs collected by the BABAR detector at the PEP-II asymmetric-energy storage rings, we obtain 2{beta} + {gamma} = (83 {+-} 53 {+-} 20){sup 0} and (263 {+-} 53 {+-} 20){sup o} assuming the ratio r of the b {yields} u and b {yields} c decay amplitudes to be 0.3. The magnitudes and phases for the resonances associated with the b {yields} c transitions are also extracted from the fit.
