Unexpectedly, Panruethai is returned to her original era, an era she has no memory of. All she knows is her powers have strengthened. Confused, she comes across a young man, Singkham, who mistakes her for a thief and apprehends her. However, she finds herself staying with him.
Five men born on the same day, Saturday the 5th, are adopted by Apichai, and join the holy road to becoming immortals. Each of them has a special power. Diao Somdet can hear voices from far away. Thoed Yodthong can disappear when he holds his breath. Don Thakradan can vast distances and spaces in his meditation. Yod Nangphaya can walk through anything that stands in his way. Kring Khlongtakhian is fast and is able to transform into whoever he wants. The five men have a mission to chase after the group of Jarga who stole a disease bomb from a laboratory in Europe and hid it in Thailand. They embark on this mission with the help of Bussakorn, daughter of Apichai who is an expert on the subject, and Duangkamol who disguises herself to investigate this case.
