Rogue One: A Star Wars Story ending explained (spoilers)

[Mai Lan]

After a panicked rush to the top of the tower, Jyn manages to transmit the plans, and the rebels damage the shield, so they can receive them. The Death Star fires a low power blast at the planet, destroying the tower (and killing Orson Krennic in the process). Most of the rebels are already dead, and the few survivors are killed by the oncoming blast, including Jyn and Cassian, their mission complete.

The rebels in space copy the plans to a card as Darth Vader arrives and starts slaughtering his way through them to retrieve the information - they're trapped behind a door but manage to get the card out and onto a ship, the Blockade Runner from the start of Episode IV, which breaks free of its parent and makes a break for it. We see the plans get delivered to Princess Leia.

It turns out that Rogue is actually Tom Lone, Crawfords supposedly murdered partner. When Rogue shot Lones wife and daughter, Lone overpowered Rogue and shot him dead. He then burned down the house, took Rogues passports and the like, and had reconstructive surgery to look like Rogue. While Rogue/Lone is battling Shiro, the leader of the Yakuza, Shiro reveals that he wanted Lone dead after wounding Rogue, and an FBI agent gave him Lones location; specifically, John Crawford. At the end, Lone shoots Crawford, maybe lethally, and kills Shiro and the Triad boss. In the next scene he is then shown getting into a car and driving somewhere, most likely to start a new life.
