Perek 1 opens with an introduction (1-3), which describes Yonah's mission and how he runs away from it, and includes the central question of the book: why does Yonah evade his mission to prophesy to Nineveh and decide to run away from God? The text does not give any explanation in the beginning of the book, and only toward the end we find an allusion to the reason. In the continuation of the perek we are told how Yonah's plan to run away from God goes awry, and God chases him into the ocean using His messengers- the storm and the fish. 

After Yonah was brought to the depth of the sea in perek 1, Yonah is trapped in the belly of a fish. In the middle of perek 2 we find Yonah's prayer to God from the belly of the fish. This prayer is a turning point in the plot, and represents Yonah's return to God.
