Nursing Home Ninjas

At 87, Marvin's eyesight is failing, but even he can't miss the bruises on his fellow nursing home residents. The staff dismisses his concerns, so Marvin begins snooping on his own. ...Unable to engage the enemy alone, Marvin enlists the aid of his two friends and fellow residents to expose the abuser and stop the abuse. Armed only with their cunning and a collection of unlikely homespun weapons, they stalk suspects, collect documents, make clandestine videos and set booby traps to impede the enemy's advance.
