For the twisted Virasoro-current algebra $\mathfrak{g}$, which is the semidirect sum of the Virasoro algebra and the twisted Heisenberg algebra, we give a complete classification of the simple weight modules of $\mathfrak{g}$ with finite weight multiplicities. In particular,  any such module is either a highest or lowest weight module, or a module of the intermediate series. We also obtain  a classification of  unitary simple highest weight modules of $\mathfrak{g}$. This is a joint work with Dong Liu and Limeng Xia.
