。
She went home.
Literal
She [topic-は] home [to-に] returned.
About as compact as a sentence gets. The verb 帰る ('return, go back') specifically means to head back to a place one belongs — home, hometown, country — distinct from 戻る ('return, go back to a previous state or place') and 行く ('go'). The に on 家 is the goal of motion. The bare past 帰った is unmarked for politeness; it's the kind of line you'd see in a diary, narration, or quick recap.
