This is one of those movies that left you wanting more. Desi Arnaz Jr. puts in a surprisingly good performance and pretty much steps out of the shadow of his famous parents. Michael Evans also showed how good an actor he was. This film pretty much dealt with a lot of issues from race relations to trust. You really see that close to the end as Cal (Arnaz's character) tries to keep Orlando (Evans' character) alive after the encounter with the shark. I often felt that this could have made a great series with the two youths traveling from port to port and showing the different encounters they had with people they met along the way. Too bad this film is rarely, if ever, shown on television anymore. This is one film that is definitely a lost treasure of the 1970's.
