The film starts out with Ike being the newest member of the Greil mercenaries. The game takes place on the (obviously fictional) continent of Tellius. The first part of the game takes place in a nation of Tellius called Crimea, where Ike, his father Greil, and others currently live.
A few hours into the game an enemy nation, Daein attacks Crimea. Ike and his new team go out to their ally nation Gallia, a nation populated by half-human half-beast creatures Laguz. While on their way there, they find Princess Elincia passed out in a bush and offer to help her, she agrees and they continue to head to Gallia
Once the Greil Mercenaries reach Gallia, Greil is killed by the Black Knight. Later in the game, you will choose to either revenge your father and kill the Black Knight, or escape and let the building crash on him (thus killing the black knight).
