Last Breath (also known as Lifebreath) makes a genuine effort to portray Cystic Fibrosis and its effects honestly, even down to the routine chest PT Martin Devoe lovingly administers to his wife Chrystie. Her rare blood type means finding a lung donor is near impossible, and as her condition worsens a desperate Martin decides the only way to save her is to find, seduce, and kill a donor himself. Chrystie figures out his plan, but can’t bring herself to warn the prospective victim. (She suddenly finds the energy reserves to follow and watch her husband, despite being bedridden and unable to tow a heavy oxygen canister for part of the movie.)
