A compactification of 11-dimensional supergravity with two (or more) walls is considered. The whole tower of massive Kaluza–Klein modes along the fifth dimension is taken into account. With the sources on the walls, an explicit composition in terms of Kaluza–Klein modes of massless gravitino (in the supersymmetry preserving case) and massive gravitino (in the supersymmetry breaking case) is obtained. The super-Higgs effect is discussed in detail.
