One possible plot could be Ianto Jones going back in time to prevent a major disaster in Torchwood's history. Maybe he travels back to the time before the Cardiff Rift opened in such a large and dangerous way. He could use his knowledge from the future to stop an alien invasion that was the root cause of the rift's instability.
The plot might involve Ianto traveling back to his own past. He could try to change certain events in his life that led him to Torchwood. For example, he might go back to when he first got involved with Lisa, and try to save her in a different way that doesn't lead to the chaos that ensued in the original storyline. This would create a whole new timeline for him and the Torchwood team.
Another idea is that Ianto travels back in time to meet some of the earlier Torchwood members, like the ones from the Victorian era. He could learn about their methods of dealing with alien threats and bring that knowledge back to his own time. This would not only be a great adventure for him but also help the modern - day Torchwood team to better protect Earth.
