Self-absorbed scientist Dr. John Kendrick (Onslow Stevens) becomes so obsessed with realising his dream of bringing the dead back to life that he neglects both his successful medical practice and his loving family, losing his wife and his mind in the process. Rather than face a stint in juvenile hall, Kendrick's son Danny (George P. Breakston) runs away from home and joins a gang in the next neighbourhood, where his lovable mutt Scooter proves popular with the other kids until it is nabbed and gassed to death by the local dog-catcher. A distraught Danny gives his father one last chance to prove his worth: teaming up with old college pals Dr. Louise Stone (Lois Wilson) and Dr. Robert Cornish (played by real life pioneering scientist Robert Cornish), Kendrick performs a revolutionary procedure to bring the mutt back from the dead.
Part heavy-handed drama, part Little Rascals-style kids' adventure, and part scientific curio, this has got to be one of the most unusual films to come out of Universal Studios during the 30s; however, despite its undeniable credentials as a genuinely bizarre obscurity, the film utilising real-life footage of Cornish's experiments on a dead dog during its climax, Life Returns offers very little in the way of real entertainment value, being too dull, depressing, and devoid of genuine entertainment value to be of much interest to anyone but the most avid fan of Universal's output.
