Wealthy young Edwin Dunwell, who is perpetually anxious about his health, meets and falls in love with Diana Lovely after accidentally causing her car to plunge into a river. Unbeknownst to Edwin, his relatives are scheming to inherit his fortune and plan to harm him. When his doctor mistakenly predicts his death at 5:00 PM, Edwin's relatives try to manipulate him into signing a new will. However, upon discovering their deceit, Edwin refuses to sign and later learns that the diagnosis was inaccurate, caused by a bee in the doctor's stethoscope. Relieved and cured of his anxiety, Edwin decides to pursue Diana, who is about to depart on a train, and persuades her to marry him despite her father's objections.
