Dan O'Hara, known as "Big Dan," returns from the war, and finding that his wife has left him, turns his home into a boys' camp and begins to train boxers. He meets Dora Allen, rescues her from an unwanted suitor, and gives her shelter in the camp. For a time, their relationship, which has become serious, is complicated by the intrusion of another suitor and by a woman who informs Dora that O'Hara is already married. The wife dies, however, and O'Hara wins Dora.
Sorry, but for now we weren't able to find movies like Big Dan.
