London, 2019. It’s the hottest June on record, and a whale is stuck in the Thames River. In the streets of the city, four old acquaintances want more from life than they’ve been given. On the summer solstice, the longest day of the year, their paths will intersect at a party that will change their lives forever…
Maggie, a once-hopeful artist turned waitress, is pregnant and preparing to move back to her hometown with her boyfriend and father-to-be Ed, leaving the city she loves and the life she imagined for herself.
Ed, coasting through life as a barely competent bike courier, is ready for a new start with Maggie and their baby, if only to finally leave behind his secret past of hooking up with strange men in train station bathrooms—and his secret past with Maggie’s best friend, Phil.
Phil, who sleepwalks through his office job and lives for the weekends, is on the brink of achieving his first real relationship with his roommate Keith. The two live in an illegal warehouse commune with other quirky creatives and idealists—the site of the party to end all parties.
As the temperature continues to climb, Maggie, Ed, and Phil will have to confront their shared pasts, current desires, and limits of their future lives together before the weekend is over.
