We present an interacting spin-2 gauge theory coupled to the two-dimensional dilaton gravity in flat spacetime. The asymptotic symmetry group is enhanced to the central extension of Diff(S^1) C^(S^1) Vec(S^1) when the central element of the Heisenberg subgroup acts trivially (vanishing U(1) level). Using the BF-formulation of the model we derive the corresponding boundary coadjoint action which is the spin-2 extension of the warped Schwarzian theory at vanishing U(1) level. We also discuss the thermodynamics of black holes in this model.
