The Frontier of the Stars

East Side gangster Buck Leslie attempts to stop a fight between chemist Gregory and a tough and is pursued by detective Phil Hoyt to a tenement roof where he takes refuge. On the roof he meets crippled Hilda Shea, who shelters him, and they eventually fall in love, the appeal of her innocence causing him to reform. Buck antagonizes the gang, however, and they try to frame him. Hoyt finds Buck on the roof, and during the ensuing fight the tenement catches on fire. Buck rescues Hilda, and she miraculously regains use of her limbs. The detective abandons his pursuit, leaving the lovers happy.
