Janet (Linda Stirling) is driving at night when one of the tyres on her car blows out. She asks chemist John Armstrong (Tristram Coffin) for some help, but this begins a nightmare for Janet involving John's jealous wife Rita (Barbara Wooddell), a hit and run Janet becomes involved in, a disappearing body and blackmail.
Private detective Steve Morgan (William Henry) helps Janet out, though often he needs some help himself from the police (Thomas E Jackson)...
The story is a little hard to follow at times but this is a fine drama, underpinned by a developing relationship between Janet and Steve which is very cute. Fast moving and squeezes a lot of plot into a short running time.
