Bonanza: The Next Generation (1988)

This is the continuing saga of the Cartwrights, only none of the original Cartwrights are here anymore but their sons appear. Ben and Hoss have passed on and Little Joe is MIA; he joined up with Teddy Roosevelt and is currently missing. Ben's brother, Aaron is now in charge of the Ponderosa, and Little Joe's wife, Annie also lives there. His son, Benjamin has come back from the East. Charlie Poke is a man who owes his life to Ben Cartwright. He is now the ranch foreman and is not exactly on good terms with Aaron. Aaron has allowed a mining company access to the Ponderosa, but the man in charge has other ideas. Hoss' son, Josh, whom no one has seen before, has come to the Ponderosa to kill Hoss because he thinks Hoss deserted him and his mother - not knowing that Hoss died before he could go back to bring Josh's mother to the Ponderosa.
