A film shows scenes of water recreation and sporting activities such as fishing, boating, walking in waterfront parks, and swimming. The film notes that infections and drowning are the primary dangers of swimming and that with the growth of safe pool facilities with lifeguards, swimmers can learn proper swimming techniques. Lynn Poole pays tribute to the YMCA, pioneers in teaching swimming and water safety. Lou Martin, Baltimore YMCA's aquatic director, explains and demonstrates the Holger-Nielsen (arm lift, back pressure) manual method of artificial respiration. The equipment used in the mechanical method is then demonstrated by Martin McMann of the Baltimore City police.
