You Have to Run Fast(1961)

Shoot First...Or Run Fast!

Dr. Frank Harlow is in the process of trying to save a man badly beaten by two gangsters whom he identifies to the police. When the victim dies the charge becomes murder and Harlow hightails it to the far woods where he finds a job as clerk Roger Condon in a sporting-goods store. Harlow's plan is to lay low until the gangsters forget about him. But complications arise from two different sectors. First, Harlow falls in love with the local beauty Laurie Maitland and second, the murderers find out where he is hiding.
