The doctrine applies only if there is evidence that the victim to be rescued is in imminent and life-threatening peril. Where the doctrine is applicable, it is a foreseeable risk that a plaintiff would attempt to rescue the victim of the defendant's negligence, to the extent that the negligence is not wanton.
