Mercy is a movie featuring a former combat surgeon battling Irish gangsters who have taken innocent patients hostage in a hospital. The premise is interesting, and the lead protagonist, portrayed by Leah Gibson, is easy to root for as she delivers beatings and bullets like a true action star. The villains, played by Jonathan Rhys Meyers and Jon Voight with a sweet Limerick brogue, are nasty enough to warrant contempt. However, Mercy suffers from a weak script that is filled with plot holes. Several scenes lack common sense and compromise self-preservation.
In Afghanistan, Captain Michelle Miller (Gibson), faces a life or death situation in a field hospital that changes her fate permanently. In the present day, Michelle works at Seattle’s Mercy Regional Hospital, where she quickly proves her exceptional skills by saving a severely injured man’s life. Her former commanding officer and current manager, Dr. Terrence (Bobby Stewart), is impressed with her abilities to think and act fast.
While the FBI interrogates Ryan Quinn (Anthony Konechny), the son of Irish mob boss Patrick Quinn (Voight), they request him to testify against his family. Ryan, a clean lawyer, knows all the dirt on his family but refuses to confess against them. The Feds decide to move Ryan to another location, and Sean (Rhys Meyers), Ryan’s violent older brother, sets up an ambush, killing many FBI agents. Rookie agent Ellis (Sebastien Roberts) rescues Ryan from the site and takes him to the nearest trauma hospital, where Michelle saves his life but discovers the extent of the conflict with the family and must fight them to protect her son (Anthony Bolognese).
