Africa 1983: Post-colonial Africa is a place for men with an eye for the main chance. Affreight Express - a charter company that doesn't ask too many questions - rides the tide of change in the newly independent Republic of Mongoma. Against a turbulent backdrop of Realpolitik and brutal rebellion, egotistical chairman Toogood Kibovo dreams of building the leading airfreight company in all Africa.
Captain William Gunn, raised in Glasgow slums, is a pilot with a past who seeks redemption in assisting Kibovo to achieve his goal. Ambitious young Australian pilot, Gary Sunnex, and troubled Kulzwanan flight engineer, Salim Njami, crew a fateful flight taking them beyond the 'Critical Point' and sets them on a dangerous path to an unknown future.
Fasten your seatbelt; Critical Point takes you into the cockpits of those anonymous jet freighters airline passengers seldom notice at airports - and into the hidden lives of the men who fly them.
