We present a Dalitz plot analysis of charmless B{sup {+-}} decays to the final state {pi}{sup {+-}}{pi}{sup {+-}}{pi}{sup {+-}} using a sample of (465{+-}5)x10{sup 6} BB pairs collected by the BABAR experiment at {radical}(s)=10.58 GeV. We measure the branching fractions B(B{sup {+-}}{yields}{pi}{sup {+-}}{pi}{sup {+-}}{pi}{sup {+-}})=(15.2{+-}0.6{+-}1.2{+-}0.4)x10{sup -6}, B(B{sup {+-}}{yields}{rho}{sup 0}(770){pi}{sup {+-}})=(8.1{+-}0.7{+-}1.2{sub -1.1}{sup +0.4})x10{sup -6}, B(B{sup {+-}}{yields}f{sub 2}(1270){pi}{sup {+-}})=(1.57{+-}0.42{+-}0.16{sub -0.19}{sup +0.53})x10{sup -6}, and B(B{sup {+-}}{yields}{pi}{sup {+-}}{pi}{sup {+-}}{pi}{sup {+-}} nonresonant)=(5.3{+-}0.7{+-}0.6{sub -0.5}{sup +1.1})x10{sup -6}, where the uncertainties are statistical, systematic, and model-dependent, respectively. Measurements of branching fractions for the modes B{sup {+-}}{yields}{rho}{sup 0}(1450){pi}{sup {+-}} and B{sup {+-}}{yields}f{sub 0}(1370){pi}{sup {+-}} are also presented. We observe no significant direct CP asymmetries for the above modes, and there is no evidence for the decays B{sup {+-}}{yields}f{sub 0}(980){pi}{sup {+-}}, B{sup {+-}}{yields}{chi}{sub c0}{pi}{sup {+-}}, or B{sup {+-}}{yields}{chi}{sub c2}{pi}{sup {+-}}.
