Simon會穿越中美洲，由加勒比海岸走到太平洋海岸。在首站的伯利茲，Simon前往北端的保護區，親睹珊瑚礁的保育成果，以及救援海牛的工作。及後他到訪Chiquibul森林，與荷槍實彈的護林員一起巡邏，追捕入侵者，上演一場刺激的槍戰！

鄰國危地馬拉過半人靠土地為生，但氣候變化導致大片地區嚴重乾旱，令農民三餐不繼。薩爾瓦多就有黑幫橫行，Simon與精英警察部隊一起走上街頭，參與打擊幫派的行動。而當地一支由青少年組成的義務急救隊，卻在黑暗中透出一線曙光。

壓軸的是哥斯特黎加，亦是生態旅遊的領先國家，全國上下推崇環保觀念，足以讓世界各國借鏡。而Simon更以一個完美方式，結束美洲之旅。

Simon Reeve continues his journey through the Americas. In this fifth leg of the journey Simon travels across Central America, from the Caribbean to the Pacific. He begins diving on a coral reef on the coast of northern Belize, and visits a rescue centre for orphaned manatees – the strange and elusive marine mammals threatened by collisions with tourist boats. In Belize’s Chiquibul National Park, Simon witnesses a gun battle between armed park rangers and intruders from neighbouring Guatemala intent on clearing the rainforest for farming. Simon’s next stop is Guatemala where over half the population live off the land. The staple crop is corn but Simon discovers that a vast area of Central America is suffering from a severe drought, partly blamed on climate change. Half of children under the age of five are malnourished in Guatemala and Simon visits one mother who only has eight days of food left to feed her young family. The drought is not only causing hunger but mass migration to the United States. In El Salvador Simon encounters the other big factor in the migration crisis, the brutal gang violence that causes thousands to flee the country. A new government in El Salvador is cracking down on the gangs and Simon heads out on patrol with an elite police unit tasked to take back control of the streets. In a dark situation Simon finds a ray of light in a volunteer organisation that takes young teenagers from gang neighbourhoods and trains them to be paramedics. The last destination on this leg of the journey is Costa Rica, a small tropical paradise that’s home to 6% of the world’s biodiversity. In a troubled region, Costa Rica is a beacon of hope and stability. It has led the world in eco tourism and aims to become the first carbon neutral country in 2021. Simon joins school children to plant trees, one of many projects to restore the country’s tropical forests and fight climate change.

Simon在美國德州與墨西哥接壤的邊境，展開第四段的美洲之旅。他與美國邊境巡邏隊一道出發，目擊一批批移民，為追求美國夢不惜非法越境。接着他進入墨西哥境內，與一位律師到訪邊境城市雷諾薩的難民收容中心，聆聽移民者的故事。雷諾薩由海灣販毒集團操控，是墨西哥最暴力的城市之一，Simon來到警方特種部隊總部，了解他們如何與配備精良的毒販鬥智鬥力。

在墨西哥南部的恰帕斯州，原住民社區難逃邊緣化的命運，更逐漸淪為二等公民。Simon深入熱帶雨林，到訪亞斯奇蘭遺址，探索先進的瑪雅古文明。蘭卡洞瑪雅人一直隱居於森林深處，與一樹一木和平共存，但外人大量砍伐森林，令他們的美麗家園面臨消失的危機。

Simon Reeve continues his journey through the Americas. In this fourth leg of the journey Simon travels from Texas and down the length of Mexico. In Texas, Simon joins the US Border Patrol who constantly pick up migrants who have illegally crossed the dangerous Rio Grande river in search of a new life in the United States. In the midst of this humanitarian crisis, Simon meets one woman who risks her life to take vital supplies across the border to stranded migrants on the Mexican side of the border in one of the most violent cities in Mexico. Much of the city of Reynosa is in the grip of a powerful criminal organisation – the Gulf Cartel. Simon visits the elite police force tasked with taking on an enemy that uses high tech surveillance and an arsenal of US manufactured weapons to control the border city. In southern Mexico, Simon visits Chiapas, a state with spectacular scenery, culture and history. Chiapas is also home to the largest indigenous population in Mexico, who trace their ancestry to the ancient Maya. In the depths of the rainforest Simon explores the Maya city of Yaxchilan, once a thriving hub of a hugely sophisticated civilization that prospered long before European settlers arrived in the Americas. Simon discovers that today’s indigenous communities have been marginalised, and many complain they’re treated as second class citizens in Mexico. Until the middle of the 20th century the Lacandon people had little contact with the outside world. Most still live in the forest like their Maya ancestors but as Simon finds out, their beautiful home could be lost to logging and farming in less than a decade.

Simon繼續美洲之旅，去到風景怡人的美國西岸，探索有「黃金之州」稱號的加州。他由北部的紅杉之鄉開始，爬上一棵76米高的巨樹，了解這種古老巨木的複製工程，以對應氣候變化。由於連年旱災，加州野火可謂一觸即發，Simon加入了當地的精英消防部隊，防止災害發生。

旅程來到美麗的太平洋西岸，Simon跟隨義務醫務人員走進洛杉磯大街小巷，見識風光背後貧富懸殊的問題。其後他南下向內華達山脈進發，與環保組織加州保育部隊會合，與一群有前科的年輕人一起工作，保護加州的山林。最後Simon來到接近墨西哥邊境一個遺世社區，為第三段旅程作結。

來到旅程的第二段，Simon進入美國，在蒙大拿州的廣闊草原上，體驗牛仔曠野放牧的滋味，深入了解農牧業的衰落。接着他來到美國草原保護區，這項野化計劃重新引入包括美洲野牛在內的瀕臨滅絶物種，希望恢復土地的自然狀態。

旅程沿着洛磯山脈向下進發，到達科羅拉多州。Simon以雙城作對照，見證美國小鎮的今昔：紐克拉城隨着舊產業沒落而日見蕭條；對比下花園城卻掌握大麻合法化的契機，收入飊升。這段旅程的終站是監獄之城卡農，由共11座監獄孕育的龐大產業，囚犯既要投入數以億美元計的勞動力，亦要為他日重獲自由的生活作好準備。

Simon Reeve continues his journey through the Americas. In this second leg Simon is in the United States travelling down the Rocky Mountains from Montana to Colorado. In wide open prairies of Montana, the cowboy way of life under threat from a long term decline in the rural economy but Simon meets a former Silicon Valley executive who has envisaged a new future for the land. The hugely ambitious American Prairie Reserve is attempting to turn 3 million acres of former ranches, farms and public lands into a protected habitat for America’s wildlife, reintroducing iconic species long extinct including the North American Bison. It’s a move being welcomed by native American groups still living under the shadow of historical injustice. Travelling south Simon explores small town America, which in recent years has witnessed a steady decline as big employers move away and people head to the cities for work. But one small town is bucking that trend - by embracing the legal cannabis industry and using the taxation raised to fund lavish local facilities. In a country with the highest incarceration rate in the world, Simon’s final destination on this leg of the journey is a Colorado town that depends almost entirely on eleven different prisons. Simon witnesses how inmates are put to work for the State, and how virtual reality is being used to prepare long term prisoners for life on the outside.

Simon Reeve展開野心之旅，他將會由北至南，征服8000公里路程，探索佔全球陸地面積逾四分一的美洲大陸。旅程從北美阿拉斯加展開序幕。在迪納利國家公園的巨大冰川上，Simon親睹全球氣候變化對這片極北之地的殘酷影響。接着他前往北極國家野生動物保護區，了解極具爭議的石油開採計劃。

Simon東行至加拿大。在亞伯達省，油砂產業雖帶來財富，卻同時對社區及原住民造成打擊，令人不禁慨嘆這個號稱環保國家的偽善。在最後一站溫哥華，他走上街頭，見證困擾這個富裕城市、以至整個北美的毒品危機。

Simon Reeve begins his most ambitious journey yet, travelling the entire length of the Americas, North to South. In this first leg of his epic journey, Simon travels from the frozen beauty of Alaska down through Canada to Vancouver and the border with the United States. Landing on a huge glacier in Alaska’s Denali National Park, Simon witnesses firsthand the brutal impact of global climate change in the remote north of the planet – ice is receding here at an alarming rate. Hunting caribou with native Americans he also hears both sides of the debate about President Trump’s plans to open the Arctic National Wilderness Reserve to oil drilling. Canada has a much greener reputation than its powerful neighbour, as Simon learns in the Yukon while sharing a bizarre cocktail containing a frozen human toe with an off-grid character called Caveman Bill. But Canada has many of its own problems: in the wealthy hipster paradise of Vancouver Simon meets the people saving lives in the midst of a brutal opioid addiction crisis that has cost so many lives across the North American continent.
