She needs to get back across the Atlantic to tell the police what happened and stop Able being executed. The gangster Brant (Francis Sullivan) must stop Jennie getting back to New York. She is travelling on a futuristic flying boat along with Brant and police detective Jim Grant (John Loder) who thinks something is up but isn't sure quite what...
Although quite far fetched this is a highly enjoyable crime drama / adventure set aboard a flying boat. A great collection of characters including prototype-geek Arnold (Desmond Tester) and plenty of good sharp dialogue.
