Cause For Alarm!

Ellen Jones, a suburban housewife, tends to her bedridden and mentally ill husband, George. Consumed by paranoid jealousy, George writes a letter to the district attorney accusing Ellen and his doctor of conspiring to kill him. After the letter is mailed, he reveals his actions to Ellen before suffering a fatal heart attack. This leaves Ellen in a desperate race against time to retrieve the damning letter before she is wrongly investigated for murder.
